Its time to get some changes, leave the exp like that, the server has less than 1k players playing, the others are just bots or merchants. I know its hard to keep players, i was ADM of a big private server before, but its been more than a year that players have no motivation to play, even with the launch of Summoner. WoE is dead, most of the famous players of WoE are playing on other servers now, just make motivation to people, not just bringing some cashes to the game. Here is some things you can add on server:
1- Buy or make yourself a gameguard, to avoid boting, anyone graduated in IT can make that.
2- Do what you did on RE:START, make quests of cash, so those who doesnt have any z or just doesnt want to spend WPE on boxes can have some chance to get those items.
3- Revitalize WoE ( Nothing to talk about that).
4- Try to get some independence, even i know iRO is linked to kRO, but doesnt mean you can't do some progress by yourself, just like bRO with Cheffenia.(Just an example, dont make Cheffenia please)
5- Make a presence program, with account bound items, anything to promote those players who actually play the server.
