Hub queue algorithms ? Which one for a group of 10 friends?

#1

Hello! I hope someone can help me please,

I have 10 friends on a hub with levels that vary from 1-7. We managed Faceit to mix the teams for us before using ELO And ELO based settings but it no longer works. Regardless of which of these two settings I pick it will not find us a game and we had to pick teams manually. Which setting is the best for group of 10 friends that want to play against each other? First in first out works every time but we often ending up with 16:2 16:3 games where when faceit picked it for us before it was well balanced.
Settings availble are:
Elo Based
first in first out
ELO
ELO low
ELO mid
ELO HIGH
ELO LOW SECONDARY
ELO LOW WITH STACKING BALANCE
ELO MID WITH STACKING BALANCE
ELO HIGH WITH STACKING BALANCE
ELO LOW WITH STACKING BALANCE SECONDARY
