Came in expecting to be disappointed OP, but your ideas are actually pretty dope. If SE decided to one day make DRK exactly like you've suggested, it'd probavly be enough to make me main it again. There is one thing I disagree with though, I do not think Delirium should take awau from any resources. It's kind of just always been that resource generator rather than consumer, and I feel like it should stay that way. So, for suggested Delirium, I believe it should simply grant the stacks of Dark Arts without consuming any Blood.

Also, LOL at the people who keep echoing "threads like this are pointless". You all can't be serious. The whole POINT of these forums is to provide feedback to the devs, trying to discourage somebody from making a post doing just that makes you look very foolish. Even if the devs won't do another complete rework, at least getting ideas in their head or simply just getting them to think about things is very good. Bottom line is, this is hands down the most boring, uninspired, and stale DRK has ever been (before people try to invalidate my opinion, I've mained DRK for years now and also leveled it to 80 weeks ago). When you set its toolkit side by side with any other Tank's, it's almost sad to see how much less depth and freedom DRK has. I mean, heck, DRK is literally the only Tank with one single target combo.
