So really what you want is to make taking a wing mission as a solo player just as profitable as taking the same mission as a wing?
Thats just.....missing the point. You want to penalise wings by splitting the reward so you as a solo player are not penalised by taking wing missions?
No.
If 4 players want to share 20mil mission by taking a quarter of the time to do it and therefore have the ability to rinse and repeat similar missions three more times before a single player could do the original mission, that all good with me. They can then do 4 mission for every mission the single player can do.
However as it stands a 4 player wing can each earn 80mil in the same time it takes a solo player to do the first mission 20 mil because they each get full pay for a quarter of the work in each mission.
Does that make sense?
