Indeed. It's a pointless and arbitrary way to restrict it. What if you have a really strong friends group of 8 players? You still have to try to get randoms to join just to hit the limit.
I imagine it will be 'restricted' in having a much higher cost/upkeep relative to the regular carriers, which would be completely fair, and allow players to make their own choice as to whether it is worth the hassle. Maybe greater penalties on jumping it around/fuelling it, that sort of stuff.
Whatever. I just find that the last carriers were already first "squadron carrier". Now one for everybody. What's the point of something which again would be called "squadron carrier", if it again would in the end be one for everybody?
Would the point merely be to have more grind? While we, as mentioned, have mostly squadron of one or two people? This carrier might be one lever to actually make squadron matter. But apparently, that is bad?
