I wholeheartedly agree with returning DA to DRK rotation, and making it change attacks to different ones will give us more variety than the current (123 until the next burst), they can use any of the old cool attacks from HW or SB which were criminally removed from DRK.

I think also another issue is that most of DRK abilities are always on CD outside of burst and we can only use them in Burst to play optimally, it will be interesting if these attacks change from (60/120 sec. CD) into (require X resource which we build up during rotation), here are some examples:

1. Living Shadow: requires 2 stacks of (Shadow Hearts), and we are granted 1 stack with each activation of (Delirium), and for allignment with the 2 min bursts we are given 1 stack at the start of the encounter
Note: I think it will fit also visually, as in (Delirium) we conjure an orb of Darkness that we put in ourselves, and on (Living Shadow) we take some of the Dark energy from us.

2. ShadowBringer: requires 2 Stacks of (Dark matter), and we are granted 1 stack with each execution of (Blood spiller, Quietus, each of the Delirium combo actions).
Note: we'll have more usability over all.

Other suggestions:

. Separate (Carve and Spit) from (Abyssal Drain), make it on a 30 Sec CD that only restores MP.

And for the single target healing:

. Re-introduce (Sole survivor), on a 60 Sec. CD that is shared with (Abyssal Drain), and make it heal from single traget with a heal potency of 500.
