How are you guys managing?

I will admit... I hate PvP in games. But I always give it a shot in each and hope that it will click. I'm running WHM and... yeah, yeah. I've heard all the talk about broken LB and lots of damage. But I kinda want to heal more. I feel awful having to cast literally anything in PvP because almost all the time it ends in CC, fatal mistake from tunnel vision, and interrupts galore.

I'm just struggling to understand the identity I'm supposed to have as a healer now. SGE has no healing outside of Kardion, AST is stuffed full of support tools, I don't know about SCH. WHM feels all over the place. I have lots of high-potency damage spells. More mitigation than healing. I don't know when to use my two Cure II charges. Feel like I'm playing way too messily and my team is probably suffering for it.

Don't know what to do. Thought I'd post this here as a final resort before I drop it for good.
