Alright so it actually does have a bane, you see once its been executed, they're actually sitting ducks for a good three seconds which is more than enough time to take them out. I main a titan, and this is how you take them out. You Also have to predict if they're about to slam you. For instance, if they're rushing or titan skating right at you, jump back there's a decent chance they'll miss their slam. Then take them out. You just gotta think fast about it.
