It is strange.
The whole Mag'Har lore is VERY interesting and thanks to Archaeology, well revealed in-game.
You are correct though, Grom was the first orc to drink Mannoroth's blood and turn the Horde into bloodthirsty, rape-and-pillage destroyers of Azeroth, and Garrosh was already born by then, whereas Thrall was not. If I remember correctly, Thrall was still very young when he escaped from Durnholde and that was after the Second War. Perhaps, Garrosh is considered "young" because he was relatively unknown 'till Thrall brought him back from Outlands and the fact that he was whiny and refusing to accept the responsibility that the position of the Leader of Mag'Har would bring (When the player arrives in Nagrand, we discover than the Greatmother is dying). Garrosh really is a much deeper character than people give the writer's credit for.

Garrosh could be older. Hes just inexperienced "noob" so thats why the orcs might call him young. Young in wisdom and so forth, maybe not psychically.

Does Time flow at the same rate in outland as in Azeroth?

That to me is an interesting question. If time moves more slowly in Outlands, relative to Azeroth, then Garrosh COULD be both 'older' and 'younger' than Thrall [older in Az, younger in physical development].

On the other hand, the 'younger' could just be in reference to his Petulent, whiney, childish personality.

I think it is because while he is older than Thrall, the fact is that no one is going to call Thrall young after he lead wars, established the new Horde, and so on and so forth.

Garrosh? Stuck in the middle of nowhere on Garadar for most of his life.

Age wise, they are prolly both considered young. Experience wise, Thrall is head and shoulders above Garrosh.

And then the characters who dislike Garrosh call him young because he acts like a two year old throwing a temper tantrum at times.

Thrall is probably younger but he most likely isn't called young as a respect type thing since he is the warchief and a shaman.

Time flowing at a different rate may help explain why we're going back in time when we do Outland, also. Although that's a little TOO convenient.

(Easy, just figure out many candles are on his cake)

Baker: Okay, there it is. Garrosh’s birthday cake. Standing at an impressive six stories tall.

Peon: A cake fit for a warcheif. What flavor is it?

Baker: Gnome.

Peon: Ah.

Baker: Well, guess there’s nothing left to do but put on the candles.

Peon: How many do you need?

Baker: (scaling a ladder up the side of the cake) Oh, well let’s see. We’re going to need one for each year so that would be…uh…(looks back down at Peon)….twen…thirt…ortyish?

Peon: (eyes widening in horror) no it’s more like…wait…it would have to be like…he’s like thirty. Right?

Baker: Dude, are you just guessing or do you really know for sure? We can’t screw this up!

Peon: (Looks around frantically and sees a grunt passing by) Hey, my man! Do you know how old the warcheif is?

Grunt: Um, like he’s got to be at least in his early thirties. Yeah, yeah like…he looks like he’s in his thirties.

Baker: But then why does everyone keep remarking on how young and reckless he is?

Grunt: Hey, hey. Hold up. Thirty is still young. You can be reckless and young at thirty.

Peon: Are you kidding me? Thirty is not young. My cousin’s thirty and he’s got a mate, two kids and a hut.

Grunt: (defensively) Well, some people aren’t willing to rush into things, okay? Listen, I’m not really a good judge of age when it comes to mag’har anyway. It’s like they go straight from being young to old men overnight.

Baker: Whoa! That’s a little bit racist.

Peon: All I know is he at least has to be younger than Thrall. They got that whole “responsible older brother/psychotic younger brother that’s a fury warrior” dynamic going on.

Baker: But then why is Garrosh brown whereas Thrall is green? That means Garrosh would have to have been conceived before Thrall.

Peon: Gross!

Baker: And why does Thrall have more hair whereas Garrosh is bald?

Grunt: (adjusting his helmet) Hey, it’s not uncommon for some orcs to go bald…earlier than others…

Peon: So, wait. How old is Thrall then?
Baker: (now descending the ladder and counting his fingers) Well, let’s do the math. He was born two years after the black portal.

Grunt: But how many years has it been since the black portal?

Peon: I don’t know. I’m not even sure how many years it’s been since we’ve killed the Lich King.

Baker: Well, it’s been enough time for Anduin Wrynn to hit puberty.

Grunt: Yeah and he looks like he’s at least thirteen.

Baker: Isn’t he kind of short though? I remember being a lot taller at that age.

Peon: Who are we even talking about anymore!?!

Baker: I need a timeline!!!

Grunt: I’ve wasted my youth!!!

Garrosh: The cake looks nice.


(All three of the orcs turn around to face their warchief)


Baker, Peon, and Grunt (In unison): HOW OLD ARE YOU?!?!?

Garrosh:….(shrugs) twenty-one?

….


Baker: …(sighs) Works for me.


(The four orcs sit on the steps of the Great Hall working their way through a keg of Dhron’s Brew)



Peon: Happy Birthday, you immature @#^%*.

actualy age doesn't affect your maturity, Thrall will have wisened up and become very mature from leading his people through a lot of crap, while Garrosh was just moping about how awful his life was for years.

@snowleopard233

Thats was so funny I laughed till I cried.

Thanks

I think Thrall should...

*distracted by fat lootz*

@snowleopard233

I love you. You made me laugh so hard when I really, really needed it.

Totally awesome.

Were you the one who posted it on the forums, or did you just find it and paste it here?

@Alassiel

I originally posted it about a week ago in the story forums. I’ve been reading the Shattering and it’s so confusing how everyone keeps referring to Garrosh as young and brash, yet they never really pinpoint how old he is. There’s not even an exact date of his birth given on wowwiki. He’s like one of those Cuban little leaguers who can play in the twelve year old division when they’re nineteen because no one has a birth certificate lol

People don't call Thrall young because he has one of those "old soul" things going on. You know, like that guildie you thought was 45 until you got into vent with him and discovered he was still a teenager. "Dude, you were recommending fiber supplements in chat!"

Garrosh is more like that mouthy kid bragging in Trade, you know, the one everyone thought was twelve but turned out to be twenty-three (and still living with mom and dad).

Hello everybody and thanks for your answers. As some of you might know I posted this question about 4 times already but never got as many and as conclusive replies.

I think we have reached the conclusion that Garrosh is older than Thrall but the later is more mature and responsible. In the past some The Queue readers answered Thrall is older and I want you to know I respect your opinion, I mean that's why i made a poll to see how many people agree with each option.

@snowleopard233

Thanks for that awesome answer, man. I'm grad to see more people asked themselves this question. Also I found on wowpedia.org and wowwiki.com some information about Garroshs possible birthday. I have to point out it is only a possible birthday.
Garrosh was sent to Garadar before Gromash drank the blood of Mannoroth and that is more than 5 years before the First War. The First War lasted about a year so ,Thrall who was born after the war, is at least 6 years younger. Now the only variable is the age Garrosh had when he got the red pox, but i personally don't think he was older than 3 years. This information is purely speculation so don't quote me on it.

Thanks again for your participation in this poll everyone and I promise I won't bother The Queue with this question again.

You sir, are win.
