So call me a depressing cynic if you like, but I know we all have gotten extremely hyped up about soon being able to sell our businesses in invite only lobbies..
However, I predict, and sincerely hope im wrong in this prediction, that Rockstar will just change the sell missions so that now if you choose to do them in invite only lobbies, you'll have overly aggressive aimbot NPC's that come after you similar to the Import/Export and Bunker sell missions when you sell alone in an empty lobby by yourself.
Because otherwise, there will no longer be any good reason to play in public lobbies ever again, ESPECIALLY if they also allow business battles to happen in invite only lobbies, but I assume those will stay public lobby only events, and would hope so.
I think there's gotta be a catch to these new changes and we're all dangerously optimistic.

If I end up being wrong and Rockstar actually makes change for the better, then I will delete this post.
