Forum:My Poison Strike Won't Activate!

Often times, when I try and use a Biotic-type Charge ability (Such as Biotic Charge, or more infamous, Poison Strike), they do not work when the button is pressed. It's extremely frustrating when I try and use Poison Strike, when it has no cooldown, and I have to keep mashing the Y button on my controller, THEN move to another area before it will even activate. I know for a fact that it requires no target to be activated. However, I noticed that in WAY TOO MANY CASES, even amongst other players, it does not charge forward when it should. I have never had this many problems with Biotic Charge, and was wondering: Why does this happen? The enemies I couldn't hit weren't even special enemies. They were: Geth Pyro, Geth Bomber, Cannibal, Husk, Scion, Centurion, Atlas, and Collector Captain. For some reason, there is an issue with the ability activating whenever I try and attack these enemies with Poison Strike. It kind of just works whenever it feels like it. Even range shouldn't be an issue for activation, yet, activation of the skill is the issue. I can stand in front of an enemy smashing the Y button with the Cabal, and will ultimately end up killing it another way, because the skill refuses to activate. Does anyone know why this is? (As I stated, cooldown is NOT the issue.)
