PS I tried the core thing and it failed to help at all

I have ATI HD radeon 4600 and I have tried 3 differnt blizz techs, they all did not help very well. They don't realize it is their game at fault here. I can play high smoothly and crash so I set it to all low and it still crashes. Updated and everything. BLUES LOOK HERE! patch it up please? I will be a very happy starcraft 2 player :) ..()_() =(-.-)= ..(bb) DO IT FOR THE BUNNY

ATI radeon HD 4600 series. I have tried suggestion from 3 differnt blizzard tech and only one realized it may be the game at fault. They think their games are so damn perfect. It will be a perfect game if services was better. Cross finger that blizzard realizes this problem
