Offering my vote for this as well. I’m alright with the Career mode and how it’s laid out, but it really is irritating when I am just in the mood to get rolling and do specific activities, yet I can’t.
My friends and I sometimes just wanna fight a fire or transport some cargo - I would rather have the ability to do that separate from the career. I understand teh logic behind making you progress through, but Career is so grindy that my friends and I have already lost interest before getting to the missions we really want.
