7.0 FATE changes you want?

[Korbei]

XP is not an issue here. As when fate farming, the xp adds up fast enough.

It really doesn't. The rough ratio of dungeon exp to fate exp is 10:1 for equal levels, assuming full completion and gold credit. You can breeze through a Duty Support dungeon in 20 minutes. (15 with a DF party but the queue makes that irrelevant, really, unless it's a roulette) You're not doing 10 fates in 20 minutes and you'd have to bust your ass to even get close.
