Blizzard knew that if Preach was at the 8.2 event he would be a problem to the direction they want to take the game in. After 10+ years of playing the game this his first offence (and an extremely minor one at that, who tf cares about a leveling exploit?) and they have gone completely overboard with their punishment. Seems to me like Blizz were just waiting for an excuse to tell him he couldn't come and this minor incident was timed perfectly for them. Someone in the comments of Preach's YouTube vid said that it seems like someone at blizzard has some sort of vendetta against him, and while it sounds silly I'm inclined to agree. The whole situation is just ridiculous, his feedback could potentially make the game much better. Shame on Blizzard.
