Not a bad idea imho. But before that there is still a problem that some missions take much more time then the server reset is performed. I think this is very nice idea, especially to give more chances to lower ranking players and then when the fractions will be implemented - but if I only see jobs, that will take me 200h to complete while server resets every 160h (approx), then I won't do much of those jobs, right?
There are not many high ranking players doing low paying jobs right now - it takes too much AP to complete those jobs for any effect
