About Warfare
I think balance for the sake of balance is a bad thing. Imagine a fighting game where every character is exactly identical. It is balanced, no doubt, but also boring. That being said, Warfare doesn't seem so overpowered at all. It is stronger than the other skills, but you can only put in 10 points and more importantly it doesn't make physical damage better than magical damage. If the wiki is correct, then a lv 20 fireball does ~1800 damage and a battle stomp ~1100. Looks fair to me.
About Bless
I am never going to use this as long it costs source points and source points don't replenish. Maybe if it could transform cursed to blessed in one cast and couldn't be countered by curse. That sounds like a nice mod, hope that is possible. Otherwise no, it is pretty useless.
