In Huttball, right at the beginnig of the matches, I usually wait at the acid, and whomever grabs the ball, I do this: Harpoon > Cyro Grenade > Neural Serge 3 seconds, 4 seconds, 2.5 seconds all The whole time they are taking a nice long acid bath. Sure they will use their abilities to remove the stun, that's why I add in Neural Serge. So Yeah I burn out three of my main abilities, but I usually kill the guy with the ball, and I pick it up and run. I've noticed that many enemy players are aware of me doing this now, which is ok, they usually wait for one of our guys to grab the ball, and then they try to get them down, I usually shield them. I also have started to have some enemy players go around me and try to push me into the acid also from behind, I usually storm to them before they can push me in. The three sec immobilization is defiantly working well, for me.
