You may connect to a friend network in your league through your only friend in this league. To try to avoid grouping with them in same league again, you may unfriend him before the end of this season.

I checked with that friend. I'm his only friend in the league.

Also, even if we were all friends, there could always be other human teams in my league, instead of all computers.

I believe you are very likely at top level of your server. But it is coincident that friends are grouped together in same league again since about 3 seasons ago,
