Its funny how this became a huge problem when the XP was changed so that you need to win to get 100% of the xp and everyone else gets only 70% (which is equal to a win 3 levels ago). Before the change there would be the occasional afk or bot. Moment the xp gets nerfed? Suddenly scores of bots/afks infesting entire teams.

Its like, since they know they are bad they wont get a win and unless their team does really well and manages to hold it then there is no reason for them to try. Understandable considering how terrible win rates are for most people. Before the change when you got equal xp to everyone win or lose you just played to have fun and get xp.
