So about Summoner...

10% vuln up, 1/6 uptime...about 16% uptime give or take?
So about 1.6% rDPS if my math's not off? https://xivrdps.herokuapp.com/encoun...vfhHVnNJdqg/18
42,184.4 * .016 = 674.9 which is close to that Nin's trick damage (657).

To have Trick count for >900 dps, total group dps needs to be about 56,500. Which is frankly ridiculous. Where'd you get numbers like that from?

Your maths are off because you are not considering a very important detail: burst. It's not because you have 16% uptime on a 10% damage up buff that you will deal 1.6% more damage overall. I'll take WAR as an example. Their IR burst window lasts 10s every 90s, so it has 11% uptime. Though IR windows accounts for 30 to 40% of a WAR's total DPS which is far from the 11% uptime.

A competent team will synchronize their raid buffs so they can maximize their damage during those.

Anyway, you can find a NIN bringing more than 900 rDPS here for example. Lots of other teams doing speedkills reach similar amounts.

EDIT: wrong link, it's fixed now.
