Aca una idea en la que cre como sera cuando llegue Illidan y vayan los primeros guilds...

Aca un quote de una entrevista a un GM:

User Demonhalo: Can you give us any insight on how thorough internal testing is on new content?

GM: Internal content testing is always going to be murky water. 40 man content must be the hardest thing to test. The tactic (IMO) that's used is bosses are unkillable when added; set to be too hard. Early guilds fights are gauged to see how they do, they wait until they think a guild has lasted long enough to be worthy of the kill then set him to die at that point, patch the servers and its job done. I don't know how it actually happens, but that's the impression that I get. Fights are also tweaked as time goes on, as new stuff gets added old stuff gets nerfed. An onyxia fight from first kill to now is a totally different thing.
