I've never really played Vigor before, but I already feel suffocated by seeing features related to crowns in various menus.
The challenges help us to progress in the battle pass that we buy with... crowns, and there are some challenges that enable us to obtain this progression but can only be completed using crowns. So basically, we pay for a battle pass and then pay to do a challenge. Also, those who are completionists in video games and cannot afford to buy more than the battle pass are stuck. I am aware that there's a reroll option (that also costs crowns), and I totally understand such business model is needed because it's a free-to-play game, but this microtransaction approach is way too aggressive.
