I posted it on the OP, for Dragoons. Well, the actual value is closer to 1+(SS-354)*0.00009 per point of skillspeed. I need to update the OP but I don't have access to my PC. That's for damage.

It doesn't affect the rate of ticks. Actually! If I remember correctly, the actual rate of ticks has never been 3s, but 2.9something.
