I still don't see how dps are not accountable for fights when Titan heart phase, ifrit ex nails, T4, T5 are all hard dps checks. If a raid wipes to any of the above mechanics, the fingers will be solely pointed to the dps. Maybe its not as obvious as a tank losing aggro or a healer not healing, but the collective dps has failed as a whole. And isn't there a saying like "you are only as good as your weakest member" or something like that.

I can kinda see where you are going with parsers, but the fact is most of the player community has not progressed to a point where parsers are necessary imho. Do you really think you need a parser for wp, ak ct or any of the hm dungeons? If SE decides to include parsers as a feature in the game, its just going to grief more players than it benefits. And serious raiders who are challenging end game content are going to get parsers one way or another, regardless of whether its allowed by SE or not.
