IMO, having DA without a cooldown or mana cost, but a mana requirement allows you to use it in emergencies to heal yourself or dump your DPS when you're frantically trying to beat enrage...is the idea behind it. I WOULD like to see DA cost 5% current HP to activate, because you're about to heal yourself a bunch, but I figure it would not be a popular idea and I doubt my TBN idea would be popular.

How would Delirium and Living Shadow work in this system? I'm not sure honestly. I'm not overly attached to LS, its Fray, woohoo, but it feels unremarkable to use. I love the current Delirium combo but there is no reason that the 1 2 3 could not turn into that during DA. Could just make Delirium boring like Bloodfest and Delirium be a 2 min CD that grants 100 Blood Gauge. yippee

The mana regen portion of this would take balancing especially since the Devs would have to trap it into the 2 min hallway that no one is allowed to leave. It would be interesting to see Abilities be able to be used in both physical and magic dmg phases, in that regard they would need to have shorter CDs like 30s or something.

That's all I can remember at this time.
