See, thats what Im saying. Why cant an MMO just have classes that have different styles of combat. It would add variety and appease so many people. Steal a class like the berzerker from Tera for a melee DPS. ... I know, I know, I have to play it, but I havent played DS2 yet - but from what I know, that style would be perfect for a tank. Any melee class has a specific kind of interrupt, or disable that allows for a moment of opportunity. Depending on how the melee class is specced, the MOO could be specific to Critical Hit, or Elemental Damage etc. The boss mechanics could do telegraphs like Wildstar combat for the melee.
Archers/Hunters have a fast rotation that works explicitly with the melee DPS that provide moments of opportunity. A Wizard takes time to cast a big spell like Ice Comet with a CD that resets upon the targeted mobs death, or if 8 seconds pass (ex.). Mana matters again to those classes. Ranged classes actually have to watch their aggro once again so its not a snooze fest out there, where as a melee DPS has a much higher aggro threshold. ...and of course, Im sure some dance dance revolution shit could be thrown around to add flare for the bored ranged class.
I feel like I would have a ball in combat like that and probably have an alt or two. *day dreams*
