If you want to allow for ranked 5s team-play, without the commitment of having 5 people, replace the old ranked 5s ladder with dynamic queue and keep soloq for those who wish to prove themselves individually. 

I have played this game since season 2 and have devoted THOUSANDS of hours and dollars into this game. Now I feel robbed and have lost a large portion of my motivation to play this game competitively and improve (the MAIN thing that makes this game so god damn good). 

As a university student, many of my old league friends have stopped playing or are at significantly different skill levels to me. Sure, I like playing with them for fun and I like the direction of pushing for more team-play and cooperation. But this really does punish people who wish to prove themselves individually and who don't have close friends of similar skill. 

I will be boycotting ranked until this system is dramatically changed and please sign this petition if you wish to bring back soloq or its equivalent in some form.
