100% Critical Chance

My IG 86 has 46% base crit chance so with his basic attack adding 50% puts him at 96% plus his unique adds 22.5% crit chance (with droids) putting him at 118.5% without HK lead... I have only ever seen his basic not crit under the debuff from B2... I think there is something going on there were it cancels out his passive crit chance gains. With HK leading he has a 148.5% chance to crit which would overcome any crit avoidance mod. Other than under B2 debuff I have never seen his basic not crit.
