Republic or Imperial?

Cagnokk (Imperial) can now craft the Reflex Barrel 27. 500k plus mats.

Fair enough. I'm just not much of a PVPer, so I don't really know how things should change for PVP from PVE.

Also, once you pick it up if you get Thermal Sensor override and Power surge. Power Surge is the ability that makes you instant cast the next ability with an activation timer. TSO reduces the heat of your next attack to 0. So, if you cast power surge, then TSO, Fusion missle can become a free, heatless attack. if you do that at the end of the rotation while you you have the 5 stacks of armor debuff up, you are GOLDEN when it comes to damage without having to worry about your heat. My heat in PVE never goes above 50, and I outdamage pretty much everyone i run with that's statted similarly. One thing to watch out for. Always try to separate unload and tracer missile with either heatseeker missile or rail shot. unload immediately after tracer missile builds heat quickly. if you can fit one of the other two attacks in there first, do it. Preferably rail shot. If you put your points in correctly, and end up getting the eliminator set for endgame, railshot costs 0 heat.
