One of the most frustrating things about GTA Online to me is the relatively poor party system, whereby moving from missions and other instances can often result in friends being split up, dumped into separate open-world parties and having to painstakingly get back together. It would have made a lot of sense for Rockstar to copy the Posse concept from Red Dead Redemption, whereby all players in a gang moved between servers together, which really is just common sense these days. The whole point of these games is to socialise and goof off with your friends, but that doesn't always seem like something that's encouraged here. Fixing this party system would enhance the social aspect, and I'd probably want to actually spend some time at my apartment if I could get a group of friends to easily join me.
