As someone with a valor lvl 73+ sage healer and sentinel, both in full BM, this patch blows.
Sentinel is entirely too easy to swat people down now. Before it was already an incredible dps class some people just couldn't get they're head around playing effectively. Now anyone with the class can be awesome even if they don't know how to focus targets or when to use their cool downs. It's become as braindead easy to succeed with as grav/tracer missle spam looked in that epic bounty hunter pvp video. I have thusly shelved my Sentinel for becoming a boring character to play that I take no satisfaction in using.
Sage healing sucks, but everyone knows that already. I'll still stick with the class whenever pvp rewards for warzones actually start making sense again, and actually ya know, look attainable.
