The "alliance of useless people" I was referring to is... lets say you had 26 people show up for dynamis. 18 people get in the main alliance, generally your core members. You form up your main alliance to peak effectiveness, but that leaves 8 people to form the remaining "alliance". The remainders were generally people that didn't have a lot of jobs leveled, or were just in general not very necessary. The external alliance often didn't have many of the luxuries that the main alliance did; you'd rarely see bard/cor, sometimes not even a decent healer, and you would always miss out on whatever important things were said in party chat. As I was often the token thief ("we don't care what you do, just tag Treasure Hunter on everything"), I know firsthand that being in that external alliance was boring as hell.
That said, yes, two party content where they both go their own ways and do their own things while assisting each other sounds great! I realize that my complaints about large-group content are often things that could have been corrected possibly by better leadership, but I just don't want to see another Dynamis rehash where have your group can be half-asleep and still do their job.
tl;dr : I'm all for larger group content, just make it active. Fun is not doing nothing but switching targets and mindlessly mowing down monsters.
