I consider you don't have any idea/experience on how HW DRK use to work on what you say, or probably you was bad playing it, no offense.

But claiming this version have more sinergy between skills, more resource management witch is false since the MP generation is much more inconsistent that HW and SB and now DRK is more anti-magic is something with all respect a ignorant will claim, specially the anti-magic part since HW DRK was know to mitigate magic better that the other 2, actually dark mind is weaker that SB so it's less anti-magic tank now.

You find the old mechanics uninteresting or to hard or no rewarding probably bcs you didn't know how they work properly it's fine but don't claim HW have inexistent lacks and problems when the job was face to face against HW WAR on damage, was literally immortal in dungeon pulls and utility was way much more impactfully than now, miss you reprisal.

BTW you gain around 4 use of edge/flood each min so you don't use never TBN to storage a dark arts for darkside, the only purpose of the proc right now is increase the amount of edge you can land on trick attack, if you have to plan the uses of edge and TBN bcs darkside you are playing the job wrong.
