I did a test. All other gears the same, +9 FAW EA9 do 2k more VP damage on same monster, but +9 HBP gives me 2 more aspd.
(I am 120S/100A, D, V/40I, L)
Theoretically +9HBP looks better. But when full buffed I can reach like 191 aspd with FAW, and HBP will give me 192/193. However because of many reasons (physical restriction on how fast human finger can press, the stupid hit lock system, how auto-guard works, etc) I found even I am at 193 aspd I can't cast VP at that same aspd level. So in this case maybe I should go with FAW?
What you guys think? I have a wakwak card, which one should I slot?
