Well, if I join DTV, people at least show some effort to work together.
On EU1 I see the same shit every round every day. Round starts, team mindlessly starts running an entire lap around the map while not looking left and right and when the fastest guys reach our own spawn again without having done anything useful, the entire team is split across the map so far that they easily get picked off by ganks one by one.
I am not really sure what stimulus is triggering this compulsive-disorder among the average crpg specimen but it is truly remarkable that people still do it to this day. Needless to say, pointlessly running over open fields makes it skeet shooting for enemy ranged while your own ranged cant counter attack, since they would have to stop moving for a few seconds to gain some accuracy, which then makes them fall behind the running melee blob even further ( where they get picked off by cav or the enemy melee blob ).
