DOTA ALLSTARS (Battle.net)
Since I get a headache playing DOTA2, and don't play it much, I stick to DOTA Allstars on Battle.net.
I'm not the best player, but I know how to be a team player. Problem is, a lot of players are so damn new that they aren't team players at all, and some insist on "going alone" (when they have no escape mechanism like blink or windwalk/lothars edge) and getting killed by 2 or more enemy heroes, particularly in enemy Jungle (neutral creeps).
Ever had it happen where a particularly bad teammate feeds hard early game, so much so that by the time your hero has anything of value, the other team's carries are too fat and you can't take them no matter what you do?
