Sargeras met his goal by possessing Medivh? I am just guessing but I think his goal was the complete subjugation/destruction of Azeroth. Granted, Medivh did a number by opening the portal on Azeroth but the champions of Azeroth have done a good job of not seeing all goodness driven off or corrupted, like it had been on Draenor. I think it is possible he might want to stick around for another shot or two.

You mentioned Khadgar seeing Sargeras before killing Medivh. I believe my statement was that no one has seen him since Medivh's death. I am really just relaying something that was conveyed by a Blizzard employee with a huge DOT DOT DOT at the end of it. I apologize if that doesn't fit into your concept of how WoW lore works.

The corrupted champion/hero is a reoccuring theme of WoW. Chris Metzen stated as much at the first Blizzcon. The source of evil in the lore is corruption from without, not something internal. Is this a basic truth? Well, leave that to the philosophers but WoW lore doesn't necessarily need to follow basic truths, does it? Even most of the races on Azeroth are the result of corruptions of the plans of the Titan. Just listen to the speech in your faction's city when someone kills Algalon or heck, go back and redo Uldaman.

I meant, his possessing Medivh was his ... sub-goal, on his way to achieve his bigger goal of destroying Azeroth. He was already in the best possible position to do that, at that time, controlling the body that was equipped with the powers of the Guardian, you can't really get much stronger than that, other than possessing an Aspect or an Old God for example. Why would he go back to Step 1, possess Med'an and do the whole thing all over again?

I mentioned Khadgar seeing him upon killing Medivh to convey that, at this time, Sargeras was still present in Medivh, and had not already "left" to implant himself into the child. So he was still there, and not in Med'an, unless he can be in two persons at the same time. Or split himself, which again, I don't think he had any reason to.

That he has not been seen since simply means that he's - rather this portion of his power, that he used in his Avatar form - is gone, imo. Although he seemed to have been defeated rather easily. (dot dot dot)

Yeah, it may be a basic truth, but it has been overdone in Warcraft/WoW. It ought to have some significance when that happens.

If you go "oh snap, another one that has been corrupted and is the new, new, new main villain, well, guess we gotta kill him now. Damn, just got back from killing three of those guys that have also been corrupted." there's definitely something wrong.

You bring up a good point about Sargeras being seen when Medivh was killed. Evelyn described the initial entry into Aegwynn as placing a part of himself in her. This is an area where Blizzard really has the ultimate freedom to do anything they want. It is fantasy and they only get into problems if they contradict themselves but not in how they explain things because ultimately it comes down to 'Oh, it's magic.'

Regarding the corrupted champion theme getting boring, I disagree. There is always going to be that next villian. How varied can you get into why they are villians? Ultimately, at some point, any true villian has gone off his/her rocker and is now doing bad things. There are cases where it is just a contest of survival between two opposed forces but that is the Horde vs. Alliance in the WoW universe.

The WoW villians are very not one-dimensional so you can't even say Blizzard is making it easy by just pointing to Old God taint.

The real thing that will make new encounters interesting are the encounters themselves and how it affects the game on a larger scale. Cataclysm looks to be one of the most revolutionary changes in the present story line ever in the WoW universe. I don't think it compares to the Sundering but that has always been ancient history.

However, oh crap, how droll... it is just another corrupted champion, Neltharion, the Earth-Warder (a.k.a. Deathwing) and this other one, Queen Azshara. *sigh* Blizzard why do you treat us so? We just got done beating Arthas, Illidan and Kaelthas... don't forget Vashj. Heck, just throw all the Eredar in there, too. /sarcasm

I personally am predicting the next corrupted champion will be Malfurion Stormrage.
