exp boost is big mistake, many servers failed cause of that, dibalancing gameplay is just crazy idea. no wonder so many servers in last 5 7 years can live more than few months... also all items higher than c grd should not be for donate too.
1st 2nd class q, hats, various accessories, various scrolls, pots etc, plz make server that ppl actually would enjoy, cause its no fun to farm for days and see how other have advantage by buying some exp boost, and getting some raid or quest first before you, but you both farm same time and you might be more skilled than donators :C
