What I am suggesting is that this innate 'greed is good' attitude by some players (enough to crowd an area) is something that can be exploited - rather than chased around Sirius until the end of time.
Because there is no way you are going to stamp it out. You are simply going to tweak the next 'best' route - and the players will move on.
That is what I mean by 'make players do the chasing'. Right now it is the devs doing the chasing, doing all the work (and as Dusty pointed out often copping wail-threads for it).
