I would love to see a new kind of mobs- an epic boss included- who are (nearly) immune to melee attacks, but
very vulnerably by magical/primal attacks.
Could be they have something like a "continual harden shell"- but very low resistance to all non-melee attacks.
Would give some biped schools and dragon casters a more important role in group fights and in game at all.
Why not start with AoP and his group- as its under examination atm anyway (let AoP and Aegors be immune to melee- leave the others as they are).
(though I have no idea how to get them down without melee^^ but would be a completely new challange).
What do you think?
