Maybe they could include the more useful skills to each class, for example every caster/healer having a version of swiftcast in their class, or each tank having their provoke, etc. This idea is already in the game with each tank class has their own version of an invulnerability buff, and how the healers used to have their own debuff cleanse. If they baked in the staple abilities to each role, we could see some interesting new role skills in the line of True North, Shirk, Mana Shift
