Engineer Builds!

After I got my 4th character at lvl 80 (it's a Warr called Beefteki), I am going to lvl up an Engineer.
Any suggestions for the items and skills? Already tried an Engi with Turrets + cond. Dmg at PvP and it rocked! The enemy was just not able to cut through my defense line of turrets at the points we captured
But tell me which builds yall use!

Hello,

here the build i use (with some changes)

You have the PVP version also:

Basically, I play p/p for single target, it allows to stack a lot of condi's and when facing a group I switch to flamethrower.
Have fun
