Honestly, I think a toggle to turn the packs' gameplay elements on and off would be best. As others have said, EA would take "EP/GP Stuff Packs" into some really shady territory in terms of pricing...because EA. You'd probably end up having those things be, like, $2 less than the full pack or they'd probably turn the concept into $5 loot boxes with 5 random items inside. Got a repeat item? Hey, you can turn it in for $0.02 for your EA wallet. Nope, not even a nickle, just two pennies...because EA. So, yeah, the toggle is the best we can hope for from the company we're dealing with here...
