I don't see why people are getting offended when I mentioned multiboxing, never did I once say multiboxing is wrong and if someone multiboxes its not my problem.

You see in a situation where people are AFK leeching you can always leave those people, kick them out, etc. Those people you have kicked out of your party obviously are going to need a secondary method to get more people to party with so they have to multibox.

Being AFK while gaining SP is the real problem here regardless of how they do it, whether it be botting, AFK leeching in a party with other players or multiboxing. Gaining SP while AFK has always been looked down upon in any MMO, why should some players get an advantage over others because of a flawed game mechanic.
