I'd rather keep role actions, but have a split between mandatory actions that we should always have access to and situational actions that we like to have in specific instances. Most of the CC popping up all over the place really should be in the latter. I don't see why you can't have Esuna in there as long as there's a slot available for it that doesn't conflict with something important like Lucid Dreaming.

Some class actions really should be in the role action list, like Tempered Will and Manaward. Both would benefit their respective roles massively.

On the other hand Protect should be removed from the role action list with gear getting a slight tweak to account for it. Ideally in the form of boosting accessory defenses. Protect should become a WHM exclusive mitigation tool available early on in ARR.

For Diversion I'd also like to see it removed entirely and instead tanks get buff for using Shield Lob/Tomahawk/Unmend in tank stance that grants a massive aggro boost for a similar period (and would persist even if you swapped out of tank stance too), making them all the standard snap-aggro opening tool. PLD would get a higher multiplier specifically to make up for having weaker overall burst generation. That isn't to say I don't care about fixing aggro issues on physical dps, but it'll come in the form of giving Invigorate the same treatment as Lucid, halving your aggro on use in addition to TP. Refresh/Tactician are likely getting merged too and with the above in mind the aggro cut can be removed on the new skill that replaces them.
