I guess my biggest problem with this game is the ridiculous spotting and minimap. If you are even remotely in any action, you are spotted like 100% of the time and people are looking at the mini-map so much, they are pre-firing where you are constantly. This game is basically who hits who first wins ADD fest. Like zero strategy/flanking. Just zerg zerg.
Just use a silencer, it's basically the only viable option unless you enjoy dying or getting shot though smoke grenades
It's one of the dumber mechanics in the game
