It only uses crit rating, so agility is safe. Crit rating elixir changes the procc, i'm not sure how a trinket with crit rating proccs/use would effect it. But i think it updates dynamically, if a trinket proccs 7k crit rating you switch from mastery->crit procc (given that the elixirs work, i doubt it makes a difference on passive and active ratings).
I would use RoRO with Juju for progress, passive mastery/crit is nice and the agi proc is good. Bad juju should work fine after the rppm changes too, 0.55 to 1.1 (typo in the table most likely). Not sure about renataki, never was a real fan of exp on trinkets locking trinket swaps. And the scaling buff isn't very nice either, annoying to keep track of even if the average stats from it is high.
