One of the first rules of WoW I learned was Big = Bad News, and the Sons of Arugal beat this lesson into my head until it stuck. Initially I thought that the size of a mob would be a great tool in figuring out what I shouldn't be fighting. I mean, if they're bigger than other stuff, how could I miss them?
So you're out in Eastern Plaguelands, merily working on your 1078th Plague Bat so Tirion can get his jollies by standing next to a hero, and suddenly your screen fills with light tan wings. You try to run, but it's too late. It's not like you can see where you're going anyways, with giant Chiroptera butt in your face. You've just been Dustwing'd.
And once you hit Outlands, it seems like there's a giant baddy around every corner. Fel Reavers roam, looking for... spare parts? Lost love? I don't know, but it was pretty obvious that I should stay away when all I could see were his hubcaps. I also give wide berth to rare striders (ok, all striders because I can't tell the difference) in Zangermarsh, dragons in about 100 different zones, and anything that looks even mildly "elitish" in stature.
It's not just the bad guys that are getting in on the sizing action, either. Those enough with the good fortune of travelling to Mount Hyjal get to see the new and improved Jaina and Thrall. I can't tell you how many jokes exploded in Vent when we first saw them. Yep, that's me next to Jaina in the picture at the top. And no, I didn't have Noggenfogger on. She's really that huge now.
So who's your favorite giant mob? Do you still suffer from weekly "ZOMG NOOO..." nightmares from EPL like me?
