While trying to find
power level if anything has been revealed for the reason behind this change, I stumbled on a post by Mania of Petopia fame over on
Mania's Arcania. For those reasons I stand by my judgment that we'll see Cataclysm in the first half of next year and we won't have another patch in power
level. There's just a complete absence of evidence to the contrary.
Perhaps 2.4 wasn't in the original timeline for
power level, I don't know. It appeared to me that it was because it very much seemed to end the whole Blood
power level story arc that brought them into the game. I've been wrong before though. Once power level is dead there really isn't much of anywhere to go with
the Wrath storyline.
The Scourge have been defeated, power level is dead and the threat of having magic-users being wiped off the face of the planet seems to be dead along with
him, the threat of
power level has been quelled. I don't see anything left. After Illidan was dead there was at least the question of "yeah but what about
the demons who were controlling him?" and that was answered with Sunwell. As power level stands now I'm not seeing any huge questions like that in Wrath.
