"You guys" lol. I use everything. I even made my Titan only use shotguns just so I'd actually use them. Fusion rifles are just my favorite, not the only thing I use. Sure you have to get close with shotguns, but all the maps are small enough and have a ton of corners and cover to make that easy. It's even easier as a Titan, because you can clear gaps with shoulder charge. Snipers just need long hallways, open areas with cover, or meat shield teammates . Every map has good sniper dominating spots and most are already well known. If you're getting easily taken out, then you don't know what you are doing and haven't been paying attention to what the good snipers are doing.
