I think that, if they want to make us regen-type spells experts, we need REALLY powerful regens to begin with. Regen IV is 30/tick, well, if we aren't getting Cure V or something similar, we need a regen-type spell that does at least 80-100 per tick. And even then, it would take the spell a good 30 seconds minimum to heal somewhat close to a Cure V. A healing helix would be nice... If only for the fact that, if it's going to tick every 10 seconds, it should heal at least 500 HP per tick, something I doubt they will do.

I really hope they surprise me with a unique spell that makes us competent at main healing but inferior to WHMs, because I don't see an easy way.
