I've been doing Normal a lot recently as MNK/THF with the suggested trusts. The fight is easy overall, though super boring. Fights take 15-20min. It's especially dull since you need to space out your WS to not cause skillchains (on MNK at least).
In the end, I had to drop Arciella II. Her Unceasing Dread would land paralyze quite often causing massive heals.
I also recommend positioning Alex so Qultada(and other trusts) are behind him. He has caused a few unintended skillchains for me.
