@Boreas-1179

people didnt complain about Dr boom at all for a year

even when all this time it was the best hero card because of how crappy warrior dk is

He was never best compared to some other DKS… guldan jaina and rexxar. Even Zuljin.

People didn’t complain before because he was matched by the dks
