I've been doing testing of my own on and off, but honestly I'd just like an answer. Is there an optimal Skill Speed? I notice just a few hundred SkSpd has a noticeable effect on the normal cooldown of combo skills, but much less with full GL, so I'm wondering where the importance lies. Getting three stacks of GL is easy when opening with RoW, so is it still worth it despite the reduced effect, or does its increase to auto attack damage make up for it? I assume auto attacks are still the MNK's largest, most consistent DPS output.
