Is aggro a good indicator for DPS?

More DMG you do to a mob the more it won't like you. When I dps on BLM I wait till the indicator turns orange facing me then pop quelling, and continue casting. I ain't gonna slow mah roll! And if the cheeky bastard decides he want's ta come my way I'll pop Manawall and light dat azz up!

There's also the issue of where different players' damage (and therefore aggro) is going. A BLM casting a bunch of AoE spells is spreading their damage around between mobs. So is a SMN who cycles between mobs to keep their DoT spells going on each of them. A character who's focusing on just a single mob until it's killed would see higher aggro levels on that particular mob but have little or none on any others.

What hasn't been mentioned yet is that crits have a 1.3 aggro bonus attached to them. So having a higher crit rate means that you will produce more aggro than you actually do dmg. This causes the aggro bar to not be a reliable measure for some dps, like bard who have an innate extra 10% crit chance bonus from straight shot.

I have ~ stable agro rate in trials. But my greed points may be 95 when i lied dead 30% of time or be 5 when my agro was high... I don't understand this mechanics at all...

Contribution in Fates and Hunts are calculated in terms of aggro and not actual damage, so you could in a way say that it's a rough indicator of your contribution to your party
