Vikk, please, don't write such nonsense! I'm curious, where did you get this from?
Despite my respect for you, I must say that the level of "grinding" and fast-clicking is roughly the same in both games, and most pro gamers don't find it difficult to switch from one to the other.
Who, when transitioning from Warcraft to StarCraft II, failed and ended up in a slump? Give me some names, please!
Grubby (Netherlands), Happy (Russia) – there are only a few who haven't fully adapted yet... but in general, the adaptation process has just begun, as StarCraft II is still a raw game.
