This is a simple but effective build I use on my Fury, just harass from far with the PPC at the beginning of the match, then go helping buddies fighting enemy mechs. You can ditch the AMS for extra MG ammos. I tried it with both light/heavy MGs but the normal ones for me seems to work better.
Tweaked this a little, including removing the AMS. Going to give this a try when it goes on sale this weekend.
