What's the point

What's the point of the extra missions, or anything, in the game when most players are PC gamers or cheaters consistently chasing you around the map as soon as you open one damn box. Jesus the devs are fucking lazy and stupid for cross play. I don't want to be the best, but I would like to grab a weapon to stand a chance against the methed out players that hop side to side or tickle your butthole with phosphorus rounds mid air as if they are tethered to a string hanging from your asshole.
