At higher levels, when you grind in an area far away from town (like Qin-Shi Tomb B3/B4), having to go repot and then run back to the spot is a bit annoying and time-consuming. It is normal for any player to try and stay out for as long as possible, just to save the 20~30 minutes of running back to their spot. As a blader grinding at B3, I used to stack up lots of MP pots, because running out of MP was the most common reason to have to go back to town. Even if I got tired after a couple hours of grinding, I used to leave my char sitting in a safe spot somewhere in the caves while I was AFK. That way I was able to grind for about 4~5 hours (not nessesarily consecutive) without having to go to town.

Yes. If you haven't had "the pleasure" to solo grind on a level 90+ chinese char, I'm afraid there's a chance your assumption to be wrong. As much as we might not like it, everyone is innocent (legit) until proven guilty (botter).
