The best argument for 4 member parties staying as is so far smh ðŸ¤¦ðŸ»â€â™‚ï¸ lol. "So what?" Obviously they just want to feel some type of control over how other players who they'd never meet or play with enjoy their day to day lives. That's basically it, from the gist of it.
I see a valid counter argument for every argument about why every single person on the planet should play a 4 member team vs. Solo, duo, trios, 5 or 6 members being on a team for those who wants it.
