Matchmaking doesnt work.

At all

I solo queue'd 3 times in a row yesterday only to be put against (self-admitted) 5 man premades with champion combos the likes i never want to see again. I just stop playing lol for a day and then try again, usually it will put me with people at my ELO, whatever that is and however it is calculated.

I have done this... The bug with this group queue is making your lowest elo teammate into the group leader into inviting all of us. With a grouping of 3 people total, with maybe a level 10 being group leading, then inviting 2 level 30s, you will fight against level 20~ no matter what. This is an easy way to play against noob which I have found playful at times after being in high elo for the longest time.
