It's outrageous to continually do that to different groups of players every couple of patches. You chaps really have my sympathy. The devs should be ashamed of themselves.
Those apologising for the devs each time they take a sledgehammer to a class need to get a clue. It wrecks the game because it's continual, on going and in the back of your mind you know it's going to impact you sooner or later.
