Also they should add a multiplier for money and experience if you decide to do solo missions.... They are a lot longer and harder to make alone and u should get rewarded if u decide to do so.
Like 1-4 mission? Then if u make it solo u get x4 bonus.
I like that idea. I think you should get bonuses for time as well. I think they should have changed job payouts for immediate replays, like if you do the same race or mission in the same "day" period then it should pay off less. But if you haven't done it for a long while then you definitely should get the payout @ 100%
The solo idea is bad and exactly what R* want to avoid. if the payout for solo was 4x, nobody would play together. Makes more sense to add a small multiplyer for each player without a death at the end. R* want people to play together, not encourage them to play alone.
primevil's idea for 24hr mission resets is good though. Maybe each time you play a mission within 24 hours, the payout (rep and money) diminishes by 5%, but is back up to full the following day (real days, not in-game). I'd extend it to all activities and not just missions.
It would be a nice way to not nerf all missions forever after doing them once, and encourage people to do various things and not farm one activity/job/race.
