I think refess cards should have more DEF or HP than they do now. The reason for this is from what I see most other factions have higher agi so the fighters are dying before they even have a chance to fight and when you revive them they just die again before doing anything.
So either give them more DEF or HP so they arn't dying so easy its not very fun when you can't even fight back.
And no the def buffs skills they have are worthless cause they only activate on the card's turn so if they have lower AGI they don't even get to use it. Broken mechanic maybe? I even brought out the 100HP guy he died in 2 attacks didn't even get to use him.
