First off all, Clemency is a very good skill, Healing team mates+ Healing yourself or pre-cast heal yourself.
Secondly, Royal Authority you can use even as MT. Just apply RoH first for the STR debuff and you should be fine.
Sheltron, Once again great skill, Not only blocks and regain mana free shield swipe.

I do have to agree you with the lack of aoe we PLD have. But i think the new skills of PLD are actually quite nice and usefull even refreshing.
