well personaly I think ether ger is the weekens on 7. If you can link Dunban's skill that heal when you crit to 7 and give 7 a mix of attack and speed gear with the sword talent art and weapons with high crit, you can heal almost an much as the enemy damages you. the aura that remove debuff and heals over time is also realy good. Or if crit is realy high speed aura is better.
