1: You mean the bf6 skins in the pass? the ones that are just a sort of tiger stripe in the colors of prior bf games? Not sure how black/blue and orange is unrealistic I literally have footage of me and some friends with a wacky painted AK at a range where it was a crazy geometric blue pink and white.
2: Everyone and their mother should understand that its because people want the BF6 cosmetics. It's no different than seeing super high twitch viewership because of drops.
What you do with your money is your own will. Nobody should be here to tell you to preorder or not. That said it is a bit strange to say you like the game but arent a fan of the skins especially as those would largely be elective. You wont really see other peoples gun skins I know I could never be able to tell you what skins my own close friends use for their guns and I play with em near daily. Also BF6 would have to be like 99% done at this point if we just had Beta and the release is in less than 2 months so there's nothing left to really change so there's no real way 2042 can directly influence the game besides post launch content which already would be planned out and developed.
