The amount you pay should be less than the additional amount you earn, since a large amount of bots will stop playing and thus they will stop extracting. All the SPS they stop earning will now be earned by other players in wild. Overall, this should be a huge upgrade to the quality of wild and serve as a good source of DEC/voucher burn.
