I with with ever one getting a big HP buff and plate classes (non-tanks) having close to the same HP as everyone else. that i i think they said that plate will not stop as much damage as it dose now and cloth and leather and mail well bee seeing a buff. all in all there slowing pvp down by a lot. so i think both druids and lock will be great locks can just dot people up and think any healing you get back will play a bigger part because you will have more time for it to come in.
with druids think they should work because you will not have to switch out and heal as much because you will not be going from full health to 0 in matter of sec. but this is just where i see pvp going from what blizz has said about trying to slow it down. i see teams that can heal being strong teams because you will have a much larger heath pull to play.

just my 2 copper. could be way off
