Because I'm too far ahead of my friends (like 1300 ELO) and none of my old Voobly friends play anymore that I've run into yet.My question is why tf is anybody solo queueing for team games? Surely that's the least fun BS possible, you get matched with terrible players who have no idea how to play the game (and potentially don't even communicate, or if they do it's because they are insulting you or your other teammates for "making bad units") and most likely have to carry the game on your own and not even receive the correct help from teammates, resulting in the team game dynamic being completely ruined and the game being a complete waste of time.
It's still a fun experience, lack of comms can be annoying but no different to other online games you single queue in. Also a lot less toxic than other ELO based games like Overwatch. Beating four-stacks is also rewarding.
