Separate ground and air vehicle squad limitation and let us have one of each without premium sub. And do not make it on the expense of the APC motorized squads.
I would suggest just adding one more slot for it by default or obtainable with silver. And do this before you release on Steam.
While I understand that you want to make money you don’t want your first impression on Steam to be “p2w” and the game being left in the gutter.
You can release only once on Steam and I am impressed with your confidence that now its the time. There was still some very pronoun but very fixable problems with the game that I expected to happen beforehand. Like better BR balance for the new players and as the suggestion I made this topic for. I hope we see them soon in the game.
Also wish you GOOD LUCK with the Steam release! I hope this game to succeed like the big brother War Thunder does now days over there.
