Only shamans got dispells @19 tho. And of course dwarfs, but that would just be stupid...Go Haste, multi-dot, collect wins? Snipe healers dispels, IE: track their dispel cooldown, and right before it comes off put a UA on whoever you think they will dispel.
The real pros dot up all three Alliance healers so they can't be sheeped and wonder why we lose mid. Don't be a pro.
