I run with this - http://www.torhead.com/skill-calc#3000cZMIk0RrzZfhbrzG.1 I think some people become too focused on their damage meter and don't pay enough attention to actually winning the objective/match. Who cares if you're doing DoT damage to a target that keeps healing it off. This build gives you some better team options. For example; the reduced CD on Jet Pack along with the PvP set bonus has been way more beneficial to the team. I will assume everyone knows how effectively Jet Pack is for many situations. I normally open combat with an instant Concussion, followed by IM, Relic, RS, and then 3x Tracers. This puts you in a perfect Unload/PS situation and I've found it to be very flexible pending your environment. Tracer Missile is just too strong to give up when you can set yourself as a turret and this build still gives you the ability to pop out nasty Railshots while still giving you a boost to the lacking Merc survivability.
