I am not yet experienced enough at the support/healer class and I think I made a mistake by rerolling one for the expansion. Sometimes it's very hard for me to switch from complete support, to holy shock/Hammer of Wrath, and than back to support. I've personally lost us a few games by simply failing to heal our warrior when I get in the "kill" mindset.
I also have a bit of trouble communicating with my teammates. I've played this game since Day 1, and some of the people on my team are fairly new (our warlock started this year and his first PvP experience was ~three months ago.) We used to go games where I would ask why we continued fighting the warrior in-range/LOS of the SoR'd Priest, etc. Even now they still aren't 100% used to every ability and aren't aware of what different team set-ups will do. We've lost matches against burst teams which I *knew* were burst, I just failed to call out.
