Thanks for all the replies btw! Wish I could reply to all individually.
-It would hurt the DPS somewhat, my vision for these AoE Buffs would last at least 30 s ~ 1 min. Wouldn't be worth it if you had to pop it every 10 sec. that would seriously put a damper on DPS. He's not an AST.

-But it's a risk and reward. You're sacrificing a cast of DPS (which you already DO when raising or having to cure anyone) to give a slight boost to your party members.

The Regain is sort of designed as a help during any sort of huge encounter, that could save the party from a wipe, which again is a sacrifice to DPS, but so is Raising and Curing.

Liked the Idea where Haste could potentially also grant a movement speed, seeing that auto attack is pointless in this game.

Thanks again guys! Look forward to seeing the future of RDM
