This question came to me and surprised me that I didn't know such a fundamental game mechanic.
When haste is applied to recast rates such as Utsusemi, when does it calculate the amount of haste in the system? Is it somewhere in mid cast of Utsusemi or at 100% cast? Aka, been wondering what to macro in for my Pld/Nin tanking build and would like to know wait times for casting, etc.
