I'm with scuro. Id like to see a "reflect" ability. Something akin to Aquaviel, that renders a status effect and a player can reflect/mimic...1~3 job abilities/spells directed at the blue Mage directly. No AoE's. The mimic ability could be recast maybe 10~20min timers and last 5min.

Maybe as an added "balance" each reflect could cost a standard 50~100mp and or TP?

And if you think about it, this could make up for the pathetic "metal skin" spell.
