I've come to the conclusion that they need to add a "/players x" command a la Diablo II. Grouping in this game is pretty terrible, it gets very laggy very quickly, the ninja looting is just plain retarded, there's no control for group leaders. They either need to add a "/players x" command or they need to remove the loot bonus from grouping. I have a thread on the POE Beta Feedback forum but it doesn't seem like many people view it or respond, feel free to support the idea over there so GGG can see it and hopefully make some changes.
I don't know how you guys are doing but I can't seem to sustain my maps playing solo, perhaps I could if I spent an absurd amount of currency on them but that's just unreasonable to ask considering how easy people have it in groups. In a group in this game you are basically playing pure carebear mode, there's extreme safety and the loot is just thrown at your feet by the monsters. Honestly I think that it's a laughable joke how people say the game is "hardcore" and so "tough" and serious when they defend the ninja looting and FFA loot garbage considering how much easier the fucking game is when playing in a group. I play on the Hardcore League and that's just garbage really, grouping is so much safer and the loot comes so much faster and easier that it's not even funny.
