One thing they should fix is Living Dead, on paper it's good to be dead if not heal to full hp, but in real time it's difficult to stay alive after using this skill, it'll be less funny to the party when they hardly reach the 100% HP to erase the effect (i tried on CT3...).

Others things is the MP consuption, it's a bit to much (but we probably get advantage of the bard/machiniste regen mp use for the healers).

As for Damage Mitigation, we get similar defense skill as War, except he can keep the -10% damage full time, we dont.

Sole Survivor should change to: "if a party member die" to "if a party member get a massive amount of damage" (let's say 60~70% of his HP).

I would love Delirium to have same effect as war damage reduction skill.
