( might as well remove dodge as well, outside of stuff like evasion )
2) Melees were balanced around having infinite resources. Casters were balanced around having finite ( or infinite, but with proper management and gameplay ) resources. The solution isn't to add infinite mana to casters and make melees do better sustained, the solution is to KEEP the previous solution going strong.
That is all. ( also, well done making ability prune so hurtful for casters as opposed to melees )
3) Remove self healing from everything but hybrids and Nerf the shit out of hybrid self healing so that its a viable way to OFF heal and help in a pinch, but not able to reliably keep their team up for X amount of time. Pure DPS classes shouldnt have self heals and Hybrids need to be punished when they heal. Make their heals cost double or even triple, so that its a last resort / desperate measure kind of thing.
