lol swtor had a pretty short log out window think like 10 mins of idle maybe more but that's not f2p yet lol. I can understand how it would help with server stress load especially in an area like ulda so perhaps the idea would work in heavily populated areas. If you want to idle in an area where there aren't a lot of people you wouldn't be hit with said forced log out but if you were to be in an overpopulated area it would force log you out based on the population of the current area and how long you've been idle for.
