Agreed, personally I don't think it should be a problem to have up to 16 friends join together and just fill in squads randomly. This is a team based game but I can understand that some players might find it discouraging to face players that actually play as a team instead on just playing on the same team, so my solution would be to split them evenly on opposite teams. This way you stick together and I suppose matches won't feel too skewed to one side.
If there are 2 big groups, then they should put each group on opposite sides and fill in the missing players with random players. They should promote faction wars, i think it would make battles more epic and they should go for server rentals instead Micro transactions (skins, so on...)
Groups under 8 or 2 squads should be kept together and over 2 squads should be split evenly on opposite teams. If they added a COMs system like squad, it would make it even better and easier to communicate between squad mates and leaders.
Yeah, I could live with team splitting if need be. However, my counter argument would be that if the option is there for people to roll in parties of 16 - more often than not you might encounter larger and organised parties as you matchmake.
It's a balancing act for sure, that in the long run, private servers might alleviate through player choice (i.e. inspect the server and player list before joining).
