Yo, I heard you liked dark arts so you can dark arts your dark arts.

Does SE even think about these things? So here's my take on it:

DA Potency increase on PS, kinda good. It's great that there's a potency buff because that will give DA+PS DRKS something useful besides a +1 enmity modifier

MP Reduction for grit; useful - now grit can be more easily used as a CD (depends on how much the reduction is though)

Dark Passenger potency buff & DA potency buff great! exceeeept, the effective potency has been REDUCED to 70/140 because recast is now 60s - not that anyone wasted 2400 mp on DP outside of dungeon trash mobs. The effect of increased enmity is great for trash mobs, but for those DRKS that use it in raids are now going to be stealing enmity; same threat management issues PLDs had when RA was on their enmity rotation in HW - is SE saying DRK MT or GTFO now?

No longer needing to DA your Dark mind to get a bonus? Awesome! DM still isn't a great CD, but FOR MAGIC busters; you can now get 30% mitigation w/o having to burn 2400 MP!

Shadow wall reduced to 120s! Ohh HELL YEA! That was SOOOOO needed!

DA+Plunge potency, more DA; but on another off-global; holy crap weaving oGCDs is going to be even more of a nightmare for DRKs
Plunge skill delay reduction! Needed! Badly
DA+Plunge now having an enmity effect? Again, going to be stealing hate - hey maybe that's SE's way of forcing DRKs to take shirk? Who knows. I know every plunge is going to be DAed for that sweeet potency buff (+140 potency AND ON A 30S OFF GLOBAL TOO!!!); you'd be nuts to not use it but people are going to hate you for using it when you're not MT)

Sole survivor hp+mp bonus even if the target doesn't die? Niiice. That's gonna be very useful, SS is finally going to get some usage outside of once on o6s and twice on o7s.

All in all, the biggest DPS gain is going to be on the DA+Plunge. Anyone that was using DP outside of dungeons will probably still use it thinking it's useful, but since it's an effective 30 potency or 100 potency (DA) loss due to the recast increase; it's still not going to be on most raiders hotbars outside of the opener if they're running MT. Second (and third and even 4th) biggest buffs are those to shadow wall, dark mind and sole survivor. Sole survivor will be used on CD to get that sweet MP boost, shadow wall got a MUCH needed recast reduction and since nobody wanted to blow 2400 MP to make their dark mind 30%; the removal of DA is a HUGE help.

The biggest issue I see though, is every 30s DRK is going to try to steal aggro with plunge having an enmity effect. Also, why so much DARK ARTS! What? Does SE really want DA to be the button pushed before ANY other button? I'm surprised they didn't give a dark arts bonus to hard slash and spinning slash. Can we get a dark arts effect to unmend, unleash, and salted earth (wait... are there really only 5 ATTACKS that don't have a dark arts effect for now?)
