How exactly does FATE credit work?

[Claire_Pendragon]

Theres been some changes to how it rates ppl, compared to before.
IDK when it happened, but recently, was the same level and gear level as my friends, and noticed i always got less exp (by 10-50%) as a tank in tank stance, than as healer or DPS. (comparing to my friends, and my own exp as the same level and iLv. on the same FATE.)
This didnt use to be the case, as tanks always maxed out more than others. But I guess the trade off, is that if you come to the FATE late, tanks build up to gold much faster than DPS/healers. You could hit the last sliver of HP, and get gold in tank stance.
But at the end of the day, you do get less exp over all as a tank, and will fall behind any friends you're playing with. (And when youre the DPS, watch ur tank friends fall behind)
No idea how it works now, as it doesnt make sense now.

Provoke has never worked on FATE targets, nor hunts for that matter.

Its in the patch notes for when it changed. And for the reason he mentions. [sarcasm] For source, Ill link you to the lodestone, where you can find it. [/ sarcasm]
