Work with me here; the next sentence about an idea is going to sound dumb, but wait for the explanation afterwards.
Perhaps if some sort of mechanism were implemented where there would be an option to randomly distribute your organized group (or squad) between the two teams, rather than keeping them all one side. A bunch of us in Discord regularly make a gigantic VoIP channel with like 8+ players; sometimes we do make 2-3 squads and synchronize queue so it's squad vs. squad, but often we also solo queue and synchronize so that we have a good chance of all getting into the same match. Personally, I find synchronized solo queue a blast because even if some of your friends are on the other team, you're still playing with your friends; it's fun to make light-hearted teases and silly retorts like, "Nooooo, stop shooting me, Greywolf!" Also, 4 times out of 5 the matches are really close; stomps are rather rare with this group synchronized solo queuing.
Therefore, I think it would be great if an option mechanism could be implemented to ensure that your preformed group (or squad) would all get into the same match, but distribute the members randomly between the two teams. Sure, currently the Rejoin Battle button works similar to this, but first you have to get everyone you want into the same match and then everyone has to remember to click Rejoin; people also may want to change loadouts too, but that can't be done with clicking Rejoin.
