DPS display could easily be solved with a system already in game.

Didn't really need a parser in XI's earlier years when everything gave you 30 minutes at the minimum to defeat something if it was in a battlefield. Most of the relevant content was outdoors and had no such restrictions, or enrages for the matter until years after the fact.

Isn't the whole reason they added Enrage because of the fact that Raiders were holding the NM's so the next spawn would be "During their window"? and they'd be holding it for hours on end just to make sure of it? It was a monopilization issue IIRC.
