Too much good loot.

The game was more exciting when you wasn't fully looted with a fully kitted ar/smg and dmr/Sr after 2 buildings. The gun fights could have way mote variety to them if the loadouts weren't all so predictable. It's basically a sniper sim.

Shotguns and sidearms might as well not exist, and it could give the mortar and rocket launchers a reason to exist as well.
