Most of the trials are Tank and spank.
Mog - still need to kill the kids before the boss.
Levi - someone still have to operation the force field switch
Garuda - OT now just has holds adds while Garuda is burned before phase II is finished.
Ramuh - Still need to break tethers with orbs; and free people affected by terror with lightning
Ultros - still need to do the mechanics.

Ifrit, Titan, Greg, Greg II, and Shiva - are just tank and spank, burn adds as they appear.
