I've been playing the Beta all morning and I'm not sure what to think.
I first rolled a Lvl 90 Warrior as a Tank, I was surprised by how few abilities there are now but I did a few dungeons and it was quite fun as tank. The dugeons are still pretty easy but are better then the rubbish in MOP.
Anyway I then decided to roll a lvl 100 Hunter, a class that I'd played since Vanilla.. again there was a lot less abilities but this time I really noticed and not at all impressed. I always play MM and I was setting up my abilities only to find that the got rid of scatter shot, arcane shot etc. Although the trap activate immediately it doesn't take into consideration travel time and with the lag of a beta it's a nightmare. When you do PVE there is so little to do it gets boring very quickly as a caster.
I can understand why some abilities have been removed but I think they've gone too far, I know there's a long way to go before release but a lot of broken classes from what I've seen so far
