Critical Potential Question

1% crit rate = 1% damage when your critical +% damage is equal to the damage of the hits of your regular attack. The higher your critical damage, the better crit rate is. So, for a BM, Hurricane does 100%, and crits add 240% without any potential or crit ring, meaning 8% crit rate > 8% total damage.

After BB, % crit rate is always worse than % total damage, because it is impossible to get more than 1.8x damage on a crit.
