How would they fix PLD 4.0?

Dark Arts Power Slash solves that, and without Grit you've got Blood Weapon up 37% of the time so you can afford it.

The thing about DAPS is no one actually feels good at using it, nor you should tbh. It's only a difference of 1x multiplier and you waste your DA that can actually do more DPS via DASE, it's still better to use normal PS combo though not optimal. All you want is to sustain aggro without ever touching PS anymore after that initial 1 slash, since you want to keep cycling mana and do all the cool stuff. DRK's mana translates to more damage in the best scenario, not to top up aggro.
