well dividing kill xp / 6 must be a bore yes; that and no jamba for quest management is why I think 2-4 is the maximum I could stand to preserve my sanity - well that and if you have more than 2 I think you're very likely to get reported all the times - but that makes the aion 6boxers all the more impressive !

ps: even with kill xp / 2 I didn't need to grind anything to reach 27 so far...
