What if you just redeemed the turret or hull for the amount of crystals (or lower) you paid for it? The point is you have hulls or turrets you don't use and they take up space in your garage. If you know you're not going to use specific equipment anymore, why not sell it and get some crystals in the process?

Do you think it might be simpler if you only got rid of the crystal drop markers? I didn't have much problem with people hanging around them and not helping the team but it might work for those who have had problems. Personally, I think that we could just reduce the amount of crystal drops, or was it just the double battle fund increasing them?
