A thought occurred to Me as I pondered the change.
Will the new attack speed be faster with haste (at top levels) than was previously possible with the old system? OR, was it designed with haste in mind to prevent the animations from "looking wrong" (As was discussed by the Dev team in the past).
If it maxxes out at BaB 20 with the old top speed (with haste, of course) , it seems like a "Nerf" (Can't think of a better word here) to any character that is not Bab 20.
I guess that after We go live with this, testing will show how much it scales between BaB levels.
I hope its not a big difference between, say, BaB 15 and BaB 20............
