The very top right most skill for defender and striker seem to add to your toughness, but the skill itself says nothing about it. anyone know if it works correctly? The defender skill is reduces cool down of super power, and the striker one reduces damage taken while using super move. when you put your cursor over either of them or select them, it will add a little bit of toughness (shown in the bars) I don't know if other classes have this, but I've asked some and they said no. maybe hunter has one for agility, and warlock has one for recovery?
