There is nothing really to maintain on the mob anymore except threat. The Delirium INT debuff might have been worthless most of the time, but the loss of Scourge does make it less exciting especially on bosses. It feels very repetitive and mundane. I won't play anything else, but I really wish they would give us another timer/debuff to keep up with while tanking.

I haven't run out of mp or lost darkside since 4.0. I don't know if they changed how quickly and how efficiently we had to manage our mp, but it seems too easy to keep mp at this point. Please don't vote me down for that comment I truly am trying to approach this neutrally from my perspective in HW. I stopped playing after the final steps of faith encounter.
