I wish you could dismantle unwanted cosmetic items received from apex packs for an amount of crafting materials (CM) equal to or ~50% of the cost unlocking the same rarity item would be...
i.e. white rarity items cost 30 CM, blue is 60, purple is 400, and gold/legendary is 1200 CM.
Obviously, if this was implemented (which I hold out no hope for), there would need to be a system put in place so when you would choose to dismantle an item you'd get a prompt that would say something like, "If you destroy this item, you'll never be able to find it again." or, "If you dismantle this item, it will be placed back into the loot pool."
Both are extremes... one way, you'll never be able to get the item again out of the apex packs, but you'll still have the option to unlock it with crafting materials... and the second way, the item will get put back into the loot pool so you'll more likely get it again later down the road and just get rid of it again... Personally, like the first option better so there's not a possibility of getting duplicates... Also if you would only get 50% of the CM back, that would still be well worth it...
This is coming from someone who doesn't have the money (any money) to spend on buying apex packs... Anyone who has the spare Apex Coin or money to buy more will do so as they please and I would if I did have the money, because this game deserves it. I believe it to be the best BR to date, given that I actually like it and haven't liked any other BR.
