Put MW on the bottom for heals is all I know. #gutted for low levels, toolkit-wise.
Everything else totally up in the air because we literally have no idea what low levels will be like. They aren't unlocked for beta testing.
We don't know about all this dumb no-stat ilvl gear people are collecting or whether it'll be useful, we don't know what stat templates(and therefore damage/healing numbers) will be tuned like.
