i haven’t played it that much since my ping was atrocious, but i would say no. IIRC beside membership and cosmetics that you can buy with gold, i think you can covert it into silver which you can use to progress faster and even buy gear but you won’t gain an unfair advantage or get something that’s exclusive to the MTX shop.
you should read what experienced players have written if you want a more detailed explanation, im just sort of vaguely familiar with the game.
heavy. heavy is good. i like heavy. sandvich.
