I've played a few games of Armada now, and while I very much love the game, if I have any complaint it would definitely center around some aspects of squadrons. The 'issues' mainly center around:
1) At the scale the game is set, it doesn't feel quite right to me how far apart the squadrons are when they're fighting against each other (or attacking a ship for that matter). Instead, when they're actually in contact with each other, it just feels somehow more 'right' and looks more cinematic to me, as at that point it is super clear that they're all fighting against each other.
2) As squadrons do tend to stay a bit spread out, it also tends to clutter up the board making it increasingly hard to find a time where you can cleanly place the ship measurement tool on the table without either pushing some squadrons out of the way or holding the measurement tool above the models (which isn't ideal, for sure).
3) It is fairly easy for the position of a squadron to get bumped accidentally out of engagement range without anyone noticing, especially when you're reaching down to adjust their damage dial and/or their activation slider. But this can even happen to a different squadron stand when you're busy adjusting another one.
