The only thing I can see as a problem is that mages (healer and casters) are punished by mp and death, where as melee and ranged are not regardless of death and can continue trucking through the dungeon or raid/endgame after they get up.

However, with the new timer on cd for lucid, I haven't found myself in any situation where mp is an issue after death and being raised (once in awhile). But we'll see how adjustments are made for the future. Only time will tell.
