It would be great if you increased the resale value of items, I bought an armor for 4500 gold and sold it for 100 gold, that's not even 2.5% of the original price.
Also, when it comes to the pvp rewards, it would be great if it was the top 100 or at least top 50 players who got a reward instead of only the top 10, otherwise it will always be the same who get the prizes and the new players will never have a shot at those rewards. Maybe you should give out more rewards with lesser value.
