i think 1 person killing for 5 would take him 10-20 times longer to hit max level than if all 5 were actively playing.
is impossible to stop afk leaching, not that i agree with it, i kick anyone from my party if they afk to long.
But i think this complain leads nowhere , theres no way to fix it.Blame the party leader who PL the rest.Then if he wants to expend over 10 times as long as what normally would take to a full party to get that sp , well, his choice i supouse lol.

Personally ? anti bot anti rmt systems plays a huge part of this game demise.people need to stop looking to what the guy in the corner is doing and focusing more on yourself and you group.Let the Gms deal with them and maybe we can have a better community all together.

Just my 3 cents.
