Bolt Escape perhaps, or a longer lasting shield, for example 10 seconds.
If they Buff healing based on Crit-Damage, they will most likely Nerf the Base-Heal a bit as well after following ZOS's recent decisions and their decisions from the past.
I would turn the bound armor skill into a passive that only requires a sorc skill slotted (get max resources automatically regardless of playstyle, get minor ward/minor resolve, and get stronger light attacks. Whichever resource is highest is buffed mag, stam, or health). When you block you get glowing eyes/aura and your block mitigation increases (similar to the psijic passive concentrated barrier).

Replace the bound armor skill with bound weapon that transforms your weapons into ones that looks conjured (maintains the same style just looks more magical). The skill has both a mag/stam morph, grants minor berserk, and heavy/light attacks can trigger a secondary affect that needs to be activated. Basically this would be a sorc version of grim focus.
