Roit, You cannot completely isolate 3s rank and 5s rank.ppl playing 3s are getting UNBALANCED games

I always get a 3s match with three diamonds in the enemy team while my team is all in silver or gold, which makes the games not even playable. Please do something with your 3s ranking system. There are still ppl playing 3s. You should somehow combine both the 3s ranks and 5s ranks to create a match, instead of completely make them two different ranking system to match ppl. IT IS NOT FAIR, and ppl are not enjoying those UNBALANCED games.
