to be honest if the concern is "exclusivity" OR if it is crowding in a persistent game OR even if it is just down to plausibility of numbers needed to fly a ship.... the minimum number to be able to feasibly expect to be able to fly a ship is imo likely to be closer to 100 than it is to 10.
if it is 10 then tbh the arguments against 10 are similar to the arguments against 1 having them.
remember an anaconda is is the size of an aircraft carrier so we are looking at a ship 10-20 times the size of that - maybe more - looking at that video....... which makes arguments against 1 player owning one the same as 10 players owning one.
Looks like only squadrons with 20.000+ members will be able to operate one.
