The development of Warcraft III has been a slow, steady progression from an innovative and ambitious title to what now appears to be little more than Warcraft II with a 3D engine tossed in but used to no great effect. This seems to be an attempt by Blizzard to justify the continued paring down of the game. "Well, look at all the people playing Starcraft running 450 mhz systems."
If they don't want "bells and whistles" in the game, they just shouldn't bother. At this late stage of development, I don't see how a survey is going to help. The feature set of the game should have been locked down already.
