Completed Trial almost with all achievements (have no one with Waterga so gonna have to find a Companion Dark Fina to reenter with). Trial was pretty damn easy, Olive and 2x Tidus chain 1 shotted Cid first wave, then focused down Cid first then Famfrit second on second wave.
Edit: Gonna leave my Olive lead with Dragon's Roar equipped in case anyone uses it for the trial.
