Turn 5 seems too difficult

[Madoka]

Conflags - Go ham on every other one. You have a 15% damage increase and they had their HP nerfed, there is no reason to ever be stuck on this phase.
Divebombs - Get on the literal edge of the field. People think they're fine being slightly into the dip and this just isn't the case. Twin will dive at an angle to cleave right through the dip. You can still dodge this but most people don't have the capability to compensate for that
Snakes - Your tanks just need to get good at positioning these. Caster LB2 will do a good 60% or more damage and lb3 should kill them outright. Get the first 2 snakes to at least 50% then use caster on all 4, the last 2 will die in no time after they have the debuff then murder Asclepius
Twisters - git gud
Dreadnaughts - blm or smn needs to slow them. If you have a smn keep twin near their spawn so they can Bane dots over. This won't transfer the slow but it will do damage. OT or whoever can needs to be stunning them. Wait for the stun timer to run out.
Hatches - OT sits in the neurolink and eats them, need to be far enough away where MT won't get hit. I've heard with echo people are using one tank and just having a melee dps eat these now.
5x liquid hells - just run in a line backwards, this should only be a problem if the MT or OT gets it.

Nothing in T5 has had it's HP nerfed.
