Questioning the design of TP

[Shaiandra]

Yeah, I understand why subtracting from the delay will scale like that, I just didn't know if FFXIV used such a formula. If I'm not mistaken it does so with defense and damage reduction too, where every X defense prevents 1% of base damage and thus its value grows as you get more of it too. Thanks for clearing it up.

Is Greased Lightning III also -0.375 GCD? Or GCD (after skill speed) * 0.85? It sure isn't GCD/1.15.
