It definitely is cool, yeah. ^_^ However, /ah does allow while the player is offline AND you can use from anywhere to whereas you can only use the sign where it is set up. As long as you can't use the shop signs to sell to the admin show (/shop), then I totally support this! Reason that I do not it to sell to /shop through the sign is due to the /sell command in the perk chest. We don't want to make that useless. :p It also makes the /setwarp perk have a bit more value as well in my opinion.
Firstly, sign shops work regardless of the owner being online or not. Secondly, sign shops work on a completely different system to
/shop so things can't be sold to there. When I say sign shop, I don't mean a shop that simply does
/shop for you (I couldn't tell what you meant) Hopefully this makes it better. Also,
/setwarp is rarer on this server than on most others so I see your point, increasing its value. If they do become too valuable, you could either allow people to make a warp (for a large sum of ingame money whilst the perk allowing it for free) or you could leave it, most likely resulting in more perk key sales and people with the perk earning money by setting warps for others (although changing perks isn't my biggest concern RN, so...) Thanks for the response :D
