A replacement ability? That's a tough question. I know as a Sorcerer-healer I always felt rather weak, particularly in PvP, and had a hard time healing properly even before the nerfs. (I'm still trying to convince my guildmates that I'm just a terrible healer, but nobody else wants to do it.) Anyway, some sort of defensive boost would be welcomed. Since consumption (and I assume its Consular counterpart) now always cost health, perhaps just a large force-burst with a long cooldown would be nice. Personally, I'd really like a toggle ability for some sort of lightning shield/armor, but I'm not sure what a suitable drawback to such a useful ability could be. (And this is totally unrelated, but why is sprint not a passive ability? Does anyone ever turn sprint off?)

In the long-term, how do you plan on handling level cap increases in terms of skill trees and skill points? Will entirely new skill trees be added or will new abilities be added to existing skill trees?
