The server is good but needs improvements to it's economy, if the server's economy is going to improve I recommend you think about doing these.
1. The "no free items" rule needs to have exceptions like for example, low tier items.
2. The "under/overpricing" rule needs to be nerfed extremely. This single rule has made trade and selling items something daring to do, making it very rare to see somebody performing a trade or buying something from another player because if that item is just a bit overpriced or underpriced could mean getting banned. I have seen so many players get banned for this stupid rule. It would be ideal to just set a limited range for how much something can cost depending on the item?
Many of the admins that are on the server don't seem fit for such a important role, for example have seen admin bases with swastikas "offensive to the Jews", I have seen players get banned for some of the stupidest reasons, I have even seen admins just ban somebody on the spot without hearing all witnesses before making a decision!
But besides that the server is good "if you play alone"
