Sell it before it gets destroyed? Sell it before it is excluded from the game and then what? Just keep using it knowing that the worst that could happen (other than being destroyed) is you can reprocess it if it is declared useless in game?
And what about that compressor array? Hmmmm decisions…
There will be some form of reimbursement when they are finally removed - my guess is 100% reprocessing. They achieved feature parity with the introduction of FLEX structures over a year ago so I’m not sure what the hold-up is. The burden of maintaining the old code must exceed any benefit from keeping it!
That compressor array depends on how far it is to the closest public structure with a reprocessing service module where you can compress your ore free of charge. Is the convenience worth the cost of fueling the tower?
