I'm pretty much reading Chill's posts and just agreeing.
SC2 is a different game than BW. It has common units, buildings, and ofc the name, but it is still a different game. It seems to me like the OP is saying that SC2 pros are just average players. That these players don't have THAT much skill. But it is pretty obvious with looking at tourney results to see that there are definitely players on another level than the rest.
