Feline should be nerfed, only to be effective at short range, as it its a SMG,
The best option is to increase the damage falloff over distance thus making it only effective a close range
in that ways guns would be used this way
Shotgun for point blank-close range
Feline for close-medium range
SCARAB for Medium Range
SCAR for Medium-Long Range
DSG-1 for Long Range
