Imagine a character with 2 major and 2 minor power tokens. 2 used with a minor token weapon (equipped first) and the 2 major ones "wasted" with 2 minor token items. Right now if you have all your power tokens used, and exchange the 2 minor token weapon with a 2 major token it won't change it, even if you have other major power tokens "wasted" in minor tokens items. So, you have to manually unequip the minor token weapon, the 2 minor token items, equip the major token weapon, and then the minor token items. What I suggest is when swaping a minor, per major power token item, the game checks if a major power token is wasted elsewhere, or maybe create a new icon for when a card is wasting a major power token.
This would be nice, along with the ability to change party order (ex: cleric, warrior, wizard -> warrior, wizard, cleric) without having to take party members in and out of the party to get the order right.
I'd definitely like to see this get into the token code. It's an impressive enough programming challenge that they got tokens working as well as they have. But yeah, it's clear that another bit of coding complexity would make gear changes simpler.
