Should it be duo/solo que?
Two good people is enough to throw things off unfortunately Have you been doing solo q? My experiences is that at least a quarter of the matches that are true random versus randoms are clown affairs where two coordinated people would certainly lead to victory. Don’t get me wrong I am very supportive of 2 and 3 man group play (its what I did when I wasnt solo I have 2 good friends that I play with sometimes) and its basically dead now sadly. Not sure what they can do. Basically you are forced into full team or solo play now unless you want to lose all the time.
two good people can throw things off. But that’s to say the duo is somehow better than everyone else for some weird reason.
As for coordination between two players, it definitely can give a slight power advantage and the mmr system they use could adjust that (they would be considered slightly higher mmr when grouped together).
Also it would probably be incredibly popular so I don’t think most matches wouldn’t feature atleast one duo on either side. At least that’s how it has been for other games with solo/duo que.
