This build is a quasi Offensive and crowd control build. Even with the use of Adrenaline now, you can still be more helpful than just providing a turret within a battle. This build primarily works best in skirmish as opposed to the DZ, although works well there too but there are just better options. The build inherently is a bit squishy so I wouldn't recommend facetanking, but if you need to, it can hold it's own as long as there is some sort of turret or seeker flame damage being applied. I normally use the MDR at range instead of the LWM4, but either should work fine. Works well especially in tight areas where there is a lot going on. As soon as a skill comes back, use it. Buffs damage and offers solid crowd control. You won't get the most kills in a match, maybe not even middle of the team, but they don't count the stats for just being a force to deal with along with a few other DPS players.
I personally like seekers, but you could use a First Aid or another skill of your choosing. There is nothing better than just flame everywhere though.
Still playing around with the build to get the perfect stat combo, but skill haste is very important on this build.
