I feel like neither of you have played it with your description.
For those that havent played -
The game has 4 types of currency, Medals, Requisition Slips, Samples and Super Credits. Medals, Requisition and Samples are only rewarded through playing the game(Either for completeing missions, or found in missions).
Super Credits can be bought with real money, but can also be found in mission.
You unlock Strategems with Requisition Slips and upgrade them(Ship Upgrades) with the Samples.
You then have “War Bonds” which are where you unlock the rest of the gear(Weapons, Armour, Boosts and more). This is where you use Medals. The War bonds are most equivilant to a Battlepass, but they are not timed and do not disappear so even if you come to the game a year later you will be able to buy and unlock everything on the very first one. The game shipped with the basic war bond that everyone had, and the first premium war bond, this is 1000 Super Credits to unlock, then you use Medals to unlock items with in it.
As for other micro transactions, there is a “Super Store” that has 4 items in it that rotate ever few days(I cant remember the time it is 2 or 3 days), that has surprisingly cheap items especially compared to what other companies are doing. They are not just purely cosmetic though, but they do not really offer anything you can not already unlock through the warbonds. Armour has different classes(Light Medium Heavy), and they have a different bonus(More Stims, More Grenades, throw grenades further) and so you might find a combination that you can not get on a warbond that you want(Light Armour with more range on grenades for example). I don’t know if I would class it as P2W, no bonus is overpowered or game changing, but it is definitely not just cosmetic.
