How about a non-support ranged dps?

[Bourne_Endeavor]

Melee healer + Judgement Nisi = ?
Melee healer + Searing Wind = ?

Those two mechanics alone make me think we aren't going to see a melee healer.

I think if said healer had ways to mitigate those types of spells, it could work. Maybe a healer version of Hallowed Ground? Or even just something like "Reduces one melee ranged attack by 50%". If Dancer were the melee healer, then I imagine a lot of their mechanics would involve dodging. So that's another way around it.
