I was trolling boosting one day in LD and found out that through knock back, valiance can render striker boost useless with a few shots. So since Callahan has the ability to interrupt enemies in PvE, does Callahan make those god dang strikers fly into the air and land on their stomaches?
Every player would get "hurt" animation when receiving any damage with any kind of weapons. However, the flinch on monsters would not ever happen on players. Yes, callahan is able to interrupt their boost for a bit time when the damage connects (which means you want a godly aim to keep hurting) but any kind of other weapons can do it too. Knock back does not have anything to do with "hurt" animation.
