Funny enough, I thought Zu was harder.

I thought the same thing.

Did Pharos with random duty finder party with everyone as a first timer. We only wiped out in Zu 2 times, other than that everything else is just a breeze.

Only need the healer to focus on party members more. Use esuna/leeches as soon as the healing debuff appears. For a fight that won't last long like this, just blow your powerful healing spell like Cure II and Cure III for WHM / Adloq and Lustrate for SCH. Use Benediction (WHM) if you think you cannot afford to save someone from charm.

For me, the priority is:
1. Charm & healing debuff
2. Charm
3. Healing debuff

I don't think Siren has any difficult mechanic at all, just healer intensive fight. Also, other ppl say that aoe healing debuff spell can be silenced/stunned, makes it even easier.
