From my experience Idris Vex/Attunement wasn't blocking dispel, especially when you have a plethora of melee hitting it (i.e. lot of fed TP).
It somehow reduces the number of spells dispelled per Dispelling Wind and greatly reduces the chance of them being dispelled, but it's nowhere near 100% resist. I had to re-do songs on BRD plenty of time, wasting Clarion Call and having to re-do the 2 fakes every time.
Vex/Attu made a *noticeable* difference of course. If you can kill within one minute it's probably not that "vital" to bother to reapply buffs I guess. Our attempts were lasting longer than 1 min though (without SP abilities).
I'm somewhat optimist about the hit rate.I think 1550 Acc is enough to cap hit rate against him (1450 Acc + Idris Torpor).
Last time we tried our DDs didn't have a lot of JPs/Gifts. Cap was 1200 back then, Reisenjima Armor wasn't that common and nobody had HQ Abj gear.
I'm pretty confident the situation nowdays would be much better acc-wise, if we were to re-try Seiryu.
Still, back then it was an important cockblock (had to stack together a lot of buffs to allow DDs to hit reliably over 90%).
Having PLD spam damaging spells sounds like a neat idea I have to say. Might be the "key" into a somewhat solid enmity retention for the tank (making the rest of the fight pisscake, because seriously the wonky enmity was the only issue on Seiryu imho)* He kept hate for the rest of the fight.
If we were to try again I'll totally have a PLD doing that instead of RUN tank.
Thanks for the tip!
