I have always wanted more support options on healers instead of just a ridiculous amount of healing skills. Maybe take something close to 1/3rd of their healing kits out and replace them with support abilities that either buff party members or debuff enemies. The only problem I foresee with that is the only buffs or debuffs this team know of are flat DPS percentage increases, so it would be hard to come up with different abilities that would essentially all do the same thing. The astrodyne system on AST right now is really a stretch to justify having seals on cards that all do the same thing.
