Post what you really hate when people do

For example... i cant stand when I play against a team of people with only rifle grenades

I hate it when people on the other team get underground on Cliffside. I figured out you can kill them with rifle grenades but it is still really annoying when they do that.

I hate it wen people glitch under the map on cliffside too, i always place a betty ther so that they cant get under without me knowing. i also hate how people hide inside the bunkers throo the barred windows on survival.

people use machine guns in a sniping map

people spam bettys around your spawn point/all hide in a room the whole match to increase their chances.

..........on middle action i need one kill for streak and almost nothing ammo.

I hate when people put a period as their name. It makes me shoot them by accident then I have to wait to respawn because I'm a team killer.
