It’s fair to say that for a lot of the community the game has become very expensive. We’re now spending millions and millions in gold and stamina just to keep on top of skills, badges and enhancements.
I think a stamina cap of 5000 and a gold cap of a million should be put on badges and adding a VIP perk for removing gold in power crafting would also help offset the rising cost of skills.
Something I would find useful is a “power craft station”. Remove power crafting from the hero section and have it in an area where you can tap on a badge, it’ll tell you how many heroes need it and the cost of creating all of them with a slider to pick how many you can afford.
Personally, I have no problems with the cost of enhancements they’ve stayed pretty consistent based on the badge colour.
