We won't be getting rid of the LLP and ELE potions as they weren't created for the sake of a KS sink. They were created as a way for users to get around the biological problems presented to their characters. On Evelon, it is still biologically impossible for beings of the opposite sex (biological, not identified gender) to reproduce. While we do support relationships of any gender (or no gender), the biological problem still exists. With the combination of magic (as magic does exist on Evelon) of science working together though, the LLP and ELE make it possible for any two beings of the same species to have offspring together if they want.
That being said, the prices probably are high by today's standards of how much users are able to roleplay. As such, there is the possibility of a price slash. The amounts I pitched when talking to Kreepy (and kinda Baal as she's in the chat, but she hasn't said anything. She tends to leave shop costs and such to us though) were 5 KS for LLP and 20 KS for ELE. We both agreed those would be pretty fair prices.
This would mean that if you're only buying a single LLP and no other potion, your cost is essentially covered by you even posting to buy it. Granted, if you're wanting to stock up on them and buy quite a few at a time, you're still taking some cost out of pocket, but it's a lot less (35 KS, which is 7 RP posts, less).
If users are concerned about it possibly taking longer than they'd like for a potion to be recorded, buy ahead. With unlimited stock potions there's no limit to how many you can buy at a time. Breed same sex a lot? Buy a few potions and if you start getting low buy some more. I understand this might not have been feasible for people at the cost of 40 KS each, but at 5 KS each it definitely should be viable. If they cost 5 KS though, you could buy 8 all at once for the price you would've paid for one originally.
As for any refunds, if we are going to slash prices, the price difference refund would be fine with me personally. The staff as a team would have to decide how far back we'd go with sending KS out, but I see no harm in giving back some of the money from recent purchases (my pitch would probably be the past 3 months).
