every single deathmatch I've played recently, 5-7 players just leave a few seconds in, leaving the lobby with half of the players and the map becomes a ghost town.
It doesn't help that 2-3 of the remaining players will either walk around the entire map or hide in a corner the entire time, which means I can run around the entire map without seeing a single person for 20-30 seconds at a time.
It's ridiculous. If riot is so adamant about keeping their shitty deathmatch like this, can they at least add a second warm-up mode with no time limit or kill limit, players can drop in drop out whenever and guns are restricted to sheriff, vandal, phantom and guardian, with walking no longer muting your footsteps? I can GUARANTEE there is a large chunk of the playerbase that would appreciate a mode like this for warming up.
