ZC needs redone too, along with a new event coin system, separate from ZC. As for trade admins, Tashkin hired them basically to overlook the trade building & try to catch scammers/glitchers, which is exactly what ZPs already did. They didn't do anything developmental & stefan/unix fired them and said not to make a position just for that.. lol. My thing with the other minerals besides graalium is those aren't ever used for sale, but are used for building bots. People buy those minerals for just a few ZC, and can create 5+ med bots that they can use at once, without having to do any work themselves. I just think the trade system has allowed for people to not do any work to get what they want in-game.
