Can players whose ranks out weight significantly the rest of the team be matched against each other?
Say the game is at a silver 5 level. But each team has a duo who has brought in a Gold 3 player. If the two gold members face other opponents than each other, then they tend to dominate their respective lanes (especially if MID or TOP). But this causes an issue if one of them is either ADC or SUP since then it is 2v2 and might not be as easy to dominate if the other (either adc or support that isn't the gold 3 player) isn't very good.
