I don't. I think it's cheap and easy to avoid anyway. When I see someone activate it I run away lol
If you run, I grapple you. But I'm thinking mostly of 2v2 Team Favor and 4 man MoC. It's pretty easy to avoid in 4v4 Team Favor or CTF.
Either way, if I'm getting worked over bad enough to get Rage, you better believe I'm at least going to cash in on one kill.
