Additional Information (Steps to reproduce/Expected behavior) :

I recently had feedback by a RDM/NIN who told me that recast timers are bonkers. He was able to reduce the recast time of Utsusemi: Ichi from 30 seconds to ~11 seconds which is lower than it possibly should be.

Spell recast timers should be capped at -50% reduction no matter the total amount of Haste and Fast Cast. https://ffxiclopedia.fandom.com/wiki/Haste_(Status_Effect) "The maximum recast time reduction from all sources is capped at 50%, and the absolute maximum amount of haste from all sources is ~80%."

UNLESS sometime in modern retail they changed this behaviour and I didn't catch it. If that's the case then I would like to know where I can change these values.

I think nobody ever accounted for stacking the 2 stats and capping that. Haste itself gets capped. Fastcast gets capped. Haste and fastcast together? we're breakin barriers! Just my theory.

There also a separate mob for "uncapped" fastcast, which is used by rare instances that ignore the rules such as chainspell/spontaneity/certain NMs that near instant cast things.
