yep, the optimal Blm rotation is too strict now.., using tools for movement usally ruins the optimal damage rotation more than ever..., and Ex1 has too much movement, if RNG is not with you (than it can iterally become impossible to even keep any rotation up, ... unless you go full SS build??)
....
let despair also give Astral Gauge stacks.., it makes the rota a little more forgiving in tight spots (might seem to make the rotation too simple.., but often due to mobility, we lose a Flare Star, which is not fun)
....
sure, getting Flare Stars off as much as possible is satisfying atm, but it becomes annoying, when losing it due to movement...
