dont make everything free, i never played woi i saw my cousin played that, i saw same like boi only pet changed like wolfking karth vit pet and etc or changed set colors. for pet cards make some zen price, and dont make too high coin rate, If all item free and everyone can get so coin so easy you cant pay with those, Make free zen but not so much, If you make the server so easy thats not so funny when you get everything after 3 min gameplay. So if you get lower coin rates, we can trade or pay with coins, or SG items. You need some item in zenhop for zen, bcoz if you have some donator you can get real cash to keep up the server and update it. Your choice you wanna make low or high rates. But lower rate=PVE server bcoz you have to do instances to get items, grinding for gold coins, deity items.
i played another Game on GM server we just added items with commands
in 4 week the full community changed xD everyone left it and new players come.
i prefer a bit lower rate, if you have to work for something. If you make the server, i can go for test.
