A suggestion for the ranked system

Adding the old "Solo Queue" to diamond and above might help with higher elo problems regarding premade and match time while maintaining the fun aspect of playing with friends that Dynamic Queue sought to bring. 5 man premades in Diamond+ are more punishing because there is lower pool of players. Thus there is a higher chance of 5man premades going up against solo queue players. If we allow Diamond+ players to only play with 1 friend that is in diamond+ and that they could only choose "fill" but are able to PREFER certain roles, it might alleviate some of the problems with Dynamic Queue for higher elo players while not affecting the rest of us who are lower in rankings.
