I started playing this build because I love the bonus of Tactician (4pc) 3 firecrest for the flame turret range and damage. It's a heavily electronics oriented build with lots of % health regen from both guns. I also run 5% extra health on kill from the mask so that I can rely on the turret killing npcs and allowing me to heal really quick.
The main objective here is to stack the 30 bullets to place the turret with 30% dmg and melt npcs at 22k/tick when going solo and over 27 when grouped. Once the turret is up the talent Tech Support will keep it up as for as long as you can defend. In resistance it's amazing how long it lasts. With the help of the turret you can hit npcs to reach 30 stacks before releasing seekers. With the right %haste combination your seekers cooldown should be ready by the time to hit 30 stacks. Rinse and repeat. Whenever I get to the next fight with 30 stacks I throw the seekers out and burn the closest npc down to re stack 30% dmg before placing the turret.
IT's a ton of damage... and I never need to run healing boxes. And its a lot of fun!
pd. I tried 4 firecrest 3 tactician and was fun too.un too.
