Main focus of this build is mid / long range pinpoint damage and suppressive fire. You have high hardpoints to exploit and you are quite fragile, so you should definitely stick with your team, poke togheter and try to fend off any push in your general direction. Left side with LPPC is for additional alpha strike against pokers (LPPC and AC5 have similar range and speed), while the right side with AC5 is your main DPS. If you are running hot, stop firing the LPPCs.
