Would you like an in-game parser?

It may not be as accurate as a parser but it will still provide you with a clue if there is something fishy going on. Good enough for me.

That's been disproven multiple times - especially due to the fact that aggro dump abilities exist. It's a false correlation that means nothing. As a bard, I usually will spam my enmity reducing ability because if I don't my threat is right behind the tanks in low level content - however because I spam it my threat usually sits near zero - yet according to my parser I am always top DPS unless there's a BLM in my party (Or SMN) and I keep Foe's Requiem on the entire fight (and sometimes I'm STILL top DPS).
