For everyone complaining about the new "Solo Queue" with premades:
A few red posts on Reddit confirmed that basically, if you're in a 5-man premade, you will be 95% likely to get matched with another 5-man premade. If you're a 4-man with 1 extra guy, you'll get matched with another 4-man with 1 extra guy. In the 5% off chance that you don't, then it will still be pretty even: for example, 4-man with 1 extra guy matched against a 3-man with 2 extra guys.
ALSO! Riot has also stated that you WILL NOT be able to queue with anyone who isn't very close to your DIVISION. Yes, Division, like I II III IV V, NOT Gold, Silver, Bronze, etc. So, you will NOT be able to be carried to a higher rank by a higher ranking player unless they are smurfing.
I hope that clears a few things up.
