Big Bang 2

I like the drop and anti leech system but Im not sure if 10 man party is the way to go I mean why not make it so that by using expeds you are allowed to merge 2 groups together like you dont gain exp from eachother but you can share party skills. Makes it way easier to boss I guess and its not really needed to have more than 6 people in your party when you grind, sometimes even less.
