Xilero crashed a lot, there is a lot of bugs and GMs are... let's tell: not very happy when you are reporting something. WoE was great in here but donation system is quite badly imballancing everything. Sadly I can recommend it only for testing your future character, which you are going to play on some low rate.

Precise, stable server with devoted GM team who cares. There are few nice customizations which are lot of fun (fishing, treasure hunting, casino...). Unique rental system and shop called "Tuzex" are alternatives to oficial Kafra shop from official servers. Reborn doesn't have any donation system (well it does but it is absolutely voluntary) because the community really stick together.
