Stop letting Silver duo with gold and gold duo with plat.
This is beyond annoying where a Gold duo with his silver who doesn't know what to do when he doesn't get MID or BOT/TOP. I keep on getting demoted because a friend who wants to help his low skill friend get to gold. If he wants to get to GOLD then HE works FOR IT not get carried. 5 games in a row I had to get a game with duo that had a silver in it, best part is that the SILVER ends up FEEDING SO MUCH. Seriously if they have a lot of win over lost then I don't mind but MANY of the SILVER has lost over win and there is a reason why they have lost over win.
I was in place in silver thanks to the rank reset but I made it to gold alone so I highly doubt they can't do it alone.
If they are in the same division I don't mind but stop bringing your low skill friend into a match where they are not that skill level and then end up feeding and ruining the match for people who BELONG in that division.
