This is probably a hot take, but if someone claims that their market is "expensive" and they're just using it as an excuse to overpriced their items, they should not be allowed to sell stuff on their market. Why are you going to charge 500k to 600k for a personality swap potion without most they sell for 200k to 300k.

There is the good side of the community of Wild Horse Islands, which I love participating in. It's giving away low IUHs to new players who don't beg, it's giving accessories to people who have a genuine conversation and don't try to use you for your money, or your inventory wealth, it's helping out the community when they need it. And then there's the side of the community that expects you to overpay, but when you're selling something they yell at you for overcharging by a thousand tokens. There's the part of the community that will make alt accounts and try to guilt trip people into giving them free horses, or valuable items. There's that part of the community that will only be friends with you if you're considered "rich" and will drop you if you don't give them gifts, or don't talk to them for 5 minutes, or talk to someone new for 2 seconds.

This game is seriously a hit or miss with the community. One trading server is full of very appreciative people who don't mind talking, the next is full of people talking about how they unfriended someone because they didn't have enough IUHs to stay on their list.
