Part of the problem is the sheer limited number of mobs combine with the fact that you actually will make significantly less in a party than just you and some trust buddies especially if you have some ilvl diff going on. Which leads to a dozen people killing everything in sight with trusts and hardly anyone teaming up pulling anything they can even when they see someone else on it until a random nm spawns and stomps them . One thing I suggest is completely eliminate the lvl/ilvl difference penalty and vastly decrease the xp share penalty so it would actually be a good idea for people to party. Would effectively increase the number of camps
