With VC and LC being added, it creates a lot of opportunities for more mission variations, especially land missions like taxi, bus, trucking, and also skimmers and rescue missions.
However, after more than 10 years, mission types haven't had massive changes. Certainly new islands and checkpoints do spice things up a bit, but the fundamental part of the server has been untouched for years. Even the new fuel trucker class is essentially the same as normal trucking.
In my honest opinion, I wouldn't mind waiting a few months more if that means more new and revamped features, such as new work classes like boating and Uber, and also revamped features like rescue, pizzaboy/courier and sky diver missions.
And if taxi and bus missions start to be logged and have the payouts increased, they would get popular easily. They at the moment are now pretty much abandoned and left to rot.
