Except that the 3 specs that bring the +5% haste buff are also those that can heal.
I know in my guild it is almost impossible to get the 5% haste buff as one by one our priests and boomkins have gone heal (and its almost impossible to find a shammy)

Plus they're changing the totems (again) - no more buff totems. The only totems in the class list so far without CDs are the two damaging fire totems and healing stream totem.

The 5% spell haste buff seems to have the most problematic makeup. Only 3 specs, vs. 3 classes in most other cases. This is such an important buff for any class with haste break points as well. (I'm mainly a resto druid, so I'm biased, but I know this affects others as well.)

@omedon666 I thought you made some very good points. However I wanted to discuss the "invalidation" of your efforts. I'm finding myself agreeing with you for the most part, but I think it needs to be said that invalidation of any progress you make on a character in this game is constantly being invalidated as patches and expansions roll out. All the work I did to get heroic gear from T12 means nothing now in T13. This can be demoralizing, especially if new content is released too quickly. At the same time, no one wants to spend a year on any particular raid instance.

The point I'm trying to make is that because WoW is a fluid, open-ended game, this will always happen. Mastering your rotation (formerly a feral druid), maximizing your stats (hello armor pen cap), upgrading your gear... none of it will be permanent. The game will continue to evolve and Blizz will try to refine the experience for players and try to improve.

I like the challenge of trying to master my class all over again and put in the work to be the best player I can be. It's the great players that can keep coming back again and again and put in the effort to reap the benefits. There's nothing wrong with hating the changes, and each player has the freedom to decide when it's time to hang it up.
