It actually depends on what you think is no-lifing. I've played for 12 hours a day, when the old Swiftswitch still was legal, there was this timer in the right corner :P (not sure if it's still there), but it wasn't really no-lifing imho and I just stopped playing when I didn't feel like it. Other people say it's nolifing training one certain skill for a whole day, others say that it's nolifing when you play for a whole day, while having fun with your online friends. I don't really have an opinion, I just think it's nolifing when you spend hours and hours just to gain a level, even when you didn't really feel like it, but just to get this certain amount of exp a day etc. But then again, you can call a person who does that "driven"
