No, it doesn't. Tracer Missile doesn't do near the damage most people seem to think it does. What's doing the damage is a properly timed Explosive Dart + 3rd Tracer + Heat Seeking Missile + Railshot. Also, Mercs that manage 450k per game are getting a lot of AoE damage from DFA. Play one in PvP before you make false assessments.
And for what it's worth, I'm a Powertech. I prefer NOT dying a dozen or more times per Warzone.
