Parry and yondu/Ironman I.F.
Ive recently noticed that parry doesn't work as its supposed to against these 2 champs (maybe more). If you parry yondu when he attacks you with his yaka arrow, I've found it particularly difficult, if not impossible, to stun him. The same goes for Ironman I.F., if he attacks you with... whatever his attack that does repulsor damage is.... that even though it may say you have parried the attack, it refuses to stun him. I even made sure that there were less than 4 molecular armor charges.
I guess what I'm saying is that maybe these champs need to be looked at more in depth to see what I'm referring to. I may be wrong, but that's what I have observed. If this ISNT a bug in the game, then kabam needs to either update the parry mastery or update those 2 champs to include parry stun immune on yaka arrow/repulsor attacks.
