Usually I gun for people like you. Once I know there is a guy spamming tracer missile/Grav round, it's open season for me. Nothing entertains me more when my force leap, kick, stasis, and push interrupt the hell out of you. And it's funny to when you just stand there with nothing else to do but get punished and roflstomped.
Tracer missile/Grav round is not OP. People just need to L2P.
