There is only one decent server - free-ro. It exists for 10 years. Active zealous administrator, stable content, confidence that the server will live 100 years, and 0 donates. Donat is not at all lol.
Of course, the server also has negative sides. Having played a lot on one-day servers, I have a family, children, I can not play as actively as I used to, so free-ro are my choice.
