First of all......are there only idiots working for Riot?
The solo-q will kill flex-q in an instant.....oh you ask why?....thats why.
Solo-q is for 1 or for 2 players premade.
Flex-q is for 1, 2, 3 and 5 players premade.
Now imagine you are a premade of 3 players in flex-q, who on earth will que up as dua or solo in flex-q ?
pretty much noone, because solo-q is there
and since solo-q is up, a team of 1, 2 or 3 are dead in flex-q.....the only whats left is 5-premade xD
there is a super solution for this...
Solo-q.....is solo-q ...... ONE player-queue !!
Flex-q is 2, 3 and 5 premades.
everyone is happy.
