Alright, so I've been having a debate with a guildie over what amounts amp and cd are equal to. Here are the standpoints:

Set Amount
-1 Amp = 2 Cd
-Cd = 3-5 Atk (Number doesn't really matter for this debate)

-Amp = x% of Base
-Cd = x% of Base

The way I see it, 1 Amp = 2 Cd is understandable, but where does that number for cd come in? Furthermore, amp and cd both say %, and when I attack a mob and get a crit, I see the HP go down by around 2.5 times my normal attack, which corresponds with my theory.

Sorry bout the bias, but I am writing this from my perspective :P

Anyways, let me know what you guys think.
