Hi, i recommend adding a itemsink into the game, before games economy becomes worse.
Could be as easy as adding a well to donate items to, with certain benefits for donating certain amount.
1:st example: donating items increase your donated $amount and have certain title for donating amount.
2:nd example: donating items decrease spec % for that donated item, 1 Ags donate=decrease 2-5% of its special outside pvp with a cap of 10-20%, dds which is cheaper= 100 dds decrease 2-5%.
3:rd example: donating items increase item defence bonus, donating a torags platebody increase slash,stab,crush bonus by 2, with cap of 30.
