I feel like the players fighting the bosses are getting cheated... I find that the full boss experience really starts at the terminal. Why not insert some nice low paying levels before the bosses, so that people aren't getting cheated out of playing the rest of the game? If they only want to play for half an hour, that could just as easily be arranged- we have the daily.
And I just don't like the arcade fee because I'm lazy and cheap.
Or we could remove mission payouts after they've been completed... that way they could just do them from the arcade and get the same experience. (and take advantage of the no arcade fee better.)
