When I started playing I did so against my better judgement. I knew about the cases and the random cards and the paying for better cases. What I didn’t fully understand was that bronze cards are actually the best in the game and they aren’t that hard to get.
Despite my lack of enthusiasm for the loadout card system in general, I think they could make it look less P2W if they made changes along these lines:
lead -> “1 star”
iron -> “2 star”
bronze -> “3 star”
silver -> “3 star / silver skin”
gold -> “3 star / gold skin”
…
Why? It makes it very clear that these cards are the same, but with a different skin.
They could even guide beginners through a bunch of missions that ended in trading-up to a bronze card.
