Low developer effort rework for the DRK Job

[Shurrikhan]

Carve and Spit and Abyssal Drain share a cooldown in EW.

I said "Abyssal" only as shorthand for "the cooldown shared by Abyssal Drain and Carve and Split." Note that I included both earlier.

(1) Keep in mind that when I proposed the trait, it was with all the other chances taking place, meaning less button bloat over the current version. An extra CaS every now and again can easily fit in that scenario.

The extra C&S per minute makes the job need its downtime generation curtailed?

(2) I say again, it is an OGCD.

That has no impact on managing the cooldown reduction per action. Management refers to having something to do in order to optimize the cooldown reduction afforded. Here, the most management to be done would be to save a Blood spender that'd need to be spent anyways before the Trick Attack window for if/when you have fewer seconds left on AD/C&S's recast time than the amount of seconds by which Souleater trim's their cooldown.

(3) 510 potency attack + MP gain feels pretty satisfying to me

You're describing C&S, but what you've suggested isn't a cooldown reduction to C&S so much as simply a Souleater buff. If you just want more C&S, and do not want necessarily to make DRK more uptime-dependent (i.e., to reduce its downtime generation) then, again, just reduce the cooldown on C&S instead of buffing Souleater to make DRK more uptime-dependent.

By all means, give us a greater frequency with our oGCD attacks that aren't simply Edge/Flood, but how you do so --while subtler-- has an effect, too.
