cause for the past 5 attempts at my promos, I keep getting troll duos, this last time, our top lane went bottom lane alistar when the roles of adc and support were already taken, and Teemo was duo'd with him defending this bullshit, saying how "its the new meta" and our top lane opponent was like 3-4 levels ahead of everyone.
This wouldn't help. Players who wish to troll will troll regardless of if they're duoed or solo.
Lane stealing/refusing to go your assigned lane is a punishable offense already.
People will troll whether they are solo or duo. Splitting up the queue will make queue time increases for everyone and in some cases, not even possible to find a match for the very high elo duo.
LOL I want to filter out Duos for the sole reason I play bot lane and 90% of the time I feel like the other bot lane is a duo on voice and I've got a laner with me in their own world totally uncoordinated xD
