It makes zero sense for the PLD class to have three different skills for AoE

[Shurrikhan]

PLD's issue is Flash and Total Eclipse fill the same role, which is spammable AoE just arbitrarily one has the enmity boost on and the other has the damage. (Though, it's similar thing for DRK with Unleash/Abyssal Drain where both have enmity boost just one does more damage and can also be used to gain life. While being TAoE instead of PBAoE...)

Not quite, though. Flash does at least offer mitigation in a way that is wasted if spammed, just as Anticipation would be wasted with, say, Raw Intuition.

I'd have to argue that now that AD's enmity modifier has been greatly increased relative to its initial state, it and Unleash are more redundant than Flash and Total Eclipse.

In any case, though, I do hope we can see them consolidated in a satisfying way, rather than just another trimming of mechanics and/or capacity.

Also, to be fair: Goring Blade has the best AoE animation in PLD's kit. A shame it, like most skills that cleave everything in front of you in their appearance, is single-target...
