LOL. I would understand if the person returns from AFK and says something like...oops I went to the bathroom. But yeah this system needs a fix.

Moreover, most, if not all, of the leechers I've run into were doing it intentionally. They, sometimes, deliberately come to the Behest camp with underrank class. Like, rank 12 at Horizon (recommended 25) and they know very well that they cannot help kill any monster. There was one underrank person at Treespeak who did that to my BF when he thought he was going to solo Behest in an abandoned camp. My BF asked him why he joined Behest and not helping, and that he's far too low rank to survive against Behest mobs. He replied, sorry I solo here. (Which means this is his normal mobs camp for EXP, I guess?) He kept joining Behest every hour and told my BF "Sorry I'm gonna stay because I solo here." Dude, OK if you want to solo, but do not friggin' leech and ruin other people's Behest. You made it so tough and don't help to kill even a single enemy. This is so disgusting.
