Conva is a decent fit on paladin now because Clemency exists. Warriors can boost Equilibrium with berserk and fancy monk feets internal release, paladins can boost (self) Clemency with Convalescence. Warrior does get a lot of benefit out of Thrill + Convalescence (and stuff like Defiance + Conva + Deployment Tactics combos), but at least they're actually getting something out of their cross class this way.

Awareness is a filler ability. Always has been. Devs couldn't think of anything else to give gladiator, I guess. Crit immunity should either be on gear or tank stances.
