I suggest that pre made teams in ranked, depending on the size of the teams, should get lower league points(LP) than those who aren't. So the more players in your pre made team the lower LP you get(obviously shouldn't be too drastic). I suggest this because it is an unfair disavantage for solo quers and I don't see the disadvantage for the pre made teams; even if solo quers get a pre made team on their team it still may not be a fair match up as sometimes the other pre made team can have better team work, communication and have more players in their pre made team. In general when playing against a pre made team it just seems/feels unfair ESPECIALLY IN LOWER ELO/LEAGUES, where team work and communication between players is hardest to get.
Just an suggestion, what are your lots thoughts...?
I'll add a poll but players in favour of teaming will choose 'disagree' ofcourse, so I don't know if it will be useful but whatever.
