Bring Back Ranked 5s Teams

I think that the main issue with ranked teams was the quantity of them. Having so many ranked teams defeats the whole purpose of ranked teams, playing competitively with friends. There are many easy fixes to this, besides of getting rid of ranked team, which will destroy communities and friendships. First, there should be more promo games, so that people who join ranked teams to mess around would never be placed. Second, there should be a maximum on the amount of teams that someone can join every set time period. This would cause less teams to play for three games, and never play again. Thirdly, ranked team mmr should be separate from solo queue mmr. A major drawback to current ranked teams is the fact that a group of friend could go undefeated and be placed in bronze, just because of their solo queue mmr. Ranked teams should be measured off of how everyone plays as a group, not solo queue rankings. If these issues were to be fixed, then there would be no reason to get rid of this featured loved by countless League of Legends players.
