Little less than unexpected news today regarding the current competitive TF2 scene, ESEA will drop it's support after Season 31 later this year. Now they have been running leagues for a while now and it's no surprise that people are getting tired of Team Fortress 2 now these days. I imagine once this final season's league is over other leagues and organizers (that still support tf2) might continue to run events still or might drop it entirely.

Will some of these teams and players that played TF2 find another game to compete in? or will they just retire from competition or just play tf2 for fun?
