I typed this a couple of times before so I feel like a broken record but I still think drivers shouldn't be permanently depletable. It says I should experiment with them but I don't want to waste them since I can't just get them back once I do. Maybe it's just a skill issue but I don't see what it adds aside from more grinding. Keeping the market wouldn't be an issue since you still benefit from having multiple of the same since you could have them both on to multiply the effect or just cycle them out while one recharges.
Though I see that a reason not to do this the game could be flooded with common drivers if there isn't a way to "destroy" them. (there could already be one but I forgot) but if a change as big as this happens adding one would probably be there too. If not just an option to sell them to the shop rather than the market for a fixed price they could add some way to recycle them. Either the mobile game one where you get like 20 of the same kind and fuse them into one that's 1% better or copy Monster Hunter and let me sacrifice a few at a time to gatcha a new one.
