Critical Chance - ability

[[MISTER]]

From Pmfun:
Critical Chance 1% chance to increase Crit.Rate when attacking +30% Crit.Rate for 15 seconds

I just got this skill from subclass and realized it only increases the crit rate by 28 flat rate.

Can someone explain why it's only 28?
Critical Rate (passive) gives +30 flat rate, so it better than the trigger. This is not right.

Thanks

Haven't been around for a while. This is correct. It is 30% crit rate,but from your base crit rate with no passive or active buffs,so you probably got around 100 crit rate,even less,so 30% from those 100 crit rate(actually less) is 28 crit rate. This buff does not benefit from the rest of your passives or active buffs.
