This build is a perfect Sniper with 900m optimal rang for all weapons (with skill). ERPPC was crazy with all the Quirks for it (Heat -10, Cooldown -15%, Velocity +10%). With skill it's possible to have this kine of weapon : Heat : 13.5 - 2.767 = 10.733 Heats Cooldown : 2.98 Sec Range : 921 m Projectil speed : 2090 m/sec With all this good staff, it's mendatory to playing with 2 of these golden weapons . Addition of Light Gauss and you have a perfect firepower at extream range for no heat. The Range, velocity & cooldown was quite identical between ERPPC Quirked & Light Gauss rifle. 16 Heatsinks just for the 2 ER PPC permit to benefit the very low cooldown (mini 4 blast before overheating). TC1 for beter zoom and velocity. Light Gauss for corner and ERPPC for hill poking. Don't shoot L-Gauss & ERPPC at the same time to avoid heat penality.
