I think PLD needs some major improvements and get rid of some of the excess buttons. Most of the 3.0 abilities could be improved.

1. Sheltron - is ok for a block that can save you damage but the side effect of gaining mp isn't useful since you really don't use MP much at all in raids.
2. Goring Blade - I don't like this ability at all it is a DoT that is just that damage over time on a Tank which really shouldn't be the ones putting dots on a boss. It was nice they gave a riot blade ender, but the effect should of been a buff or debuff effect not a dot.
3. Divine Vale - a slight aoe shield which needs to be triggered by a heal, would be more useful if it just activated when you pressed it but over all not too useful due to its long cooldown healers shouldn't have trouble shielding or healing aoe damage to start with often it just feels like this move isn't needed.
4. Clemency - Paladin often the main tank really shouldn't be using this because it has a cast time and often you will get interrupted. This ability should be instant cast otherwise its never used in raiding. Only has utility when trying to solo harder stuff or old content.
5. Royal Authority - I really this like this move, they gave an alt ending for the RoH combo but RA does nothing but higher potency. This is bad in the overall meta of the game. Because this move has no enmity bonus you can lose hate to warriors since their enmity finisher butchers block is their highest potency move. Honestly this move feels wasted, the high potency finisher should be baked into RoH like warrior, Royal Authority should do lower damage and do some kind of buff or debuff instead.
