If you want to have a interesting warserver that people will play for more than an hour then logg out you need to make it interesting. I think you should make private accounts that drops 1-0.5 levels per death for people that want to stay on the servers and of course 1/1 accounts for people that just want to try out the servers. And also add something like frag\death points so you can compare players (i think level is not good enough for this because the level gain can't be high so newer players have 0 chance to kill older players, frags/deaths shown next to level works better for this) Maybe you could also cash in frags (maybe 1000 gp per frag) and buy something for it (knights upgrade fire sword>bright sword>giant sword>sov, paladins get power bolts and all vocations gets more supplies, maybe with 2-3 charges to make bought runes more valuable)
Make sure you pm me when you open the server!
