I do not mean disrespect, but I just do not see the problem.
POBS are meant to be a pseudo endgame thing, so of course they are costly. Change is just to make pobs decay two times faster WHEN they haven o resources to work, so, where is the problem????
Literally with a well suited hydroponics and like 20k fertilizers you have to refill a POB every 10 days? maybe if you want to go crazy 15? I think thats a huge change to the old model.
