Oooh I've failed KQs countless times. Pretty much fail due to the players not being sure what to do, or just being an ass in general.
Can't really think of any other reasons why I would fail a KQ other than that. I guess if there's no tank or something too.... but I did complete a Mara KQ without tanks (dpsers took turns running away from boss, then dying, get ressed, rinse and repeat).
Not sure if I completed a KQ without a cleric yet.. so I guess having no clerics is a problem...
Other than that, it's mainly due to lack of competent players in the KQ. XD
