TBH, is prefer a monthly patch more than monthly cards or cosmetics. There’s already all those reasons for not getting new cards (outside of expansions) and how do you expect CP to make money if they go around handing cosmetics out like people hand out tissues in manga? It’s a F2P with cosmetics and more cards being part of their marketing strategy.
At least with a monthly patch, they could go about making quality of life improvements (like a slider for match replays?)
