I think you should make a double check on payments just INCASE someone clicks on something by accident (Ignore this one if you meant it when you said “we will add reminder of payment to the game”), Plus:
1) as far as I’ve seen, there is a really good amount of items in, but the “Bind” system is kind of overly strict. I think as far as it is right to keep an upgraded item bind because It’d be easy to trick someone to pay a lot for it, I still think it should at the very least be transferable to another character or a clan guild member.
2) the game is pretty damn amazing, But I think it could be a little less expensive on diamond and gold wise.. It gets annoying after a while to see a cash sink, If you do the math, would you rather earn 100$ over a course of a year or 20$ a month and they quit?
3) you should really look on the server at some point, players are raising, and the lag would really cause them to quit, there is almost minimal lag, However.. during the past week or two, a lot of lag spikes have happened and it caused the server to be a little.. slow, even in pvp.
and last but not least, 4) the game could really use a better guild system, could focus a day or two on some minor but nice updates, Like more ranking on the guild system, than just 1 rank, and a guild war option would be great, Looking forward to share some more ideas when I have them. :) thanks for taking your time to read this.
