To be fair, We've been undefeated on our mains killing people about as effectively since level 10. Now, we weren't killing entire teams by ourselves then, but in a 3 man group, we are undefeated. This isn't so much an issue of any one mechanic so much as it is... people are bad. He has been rolling people before he had tracer missile. I don't think it's any more broken now than it was then. Also take a look at IAs and Smugglers, their stealthers can kill anybody in 3 shots, including Xurge. so I don't think it's too broken.
