There aren't really any great Rappelz servers left... Most are all the same, super high rates and pvp... But players are spread too thin across all of these similar servers.
There is one good server I have seen, called
. It's not too shabby, but it has 2 servers, one for PvE and one for PvP. Still needs work if it wants to be the best, but definitely better than any of the others. The staff is active, and they are working on updates. Haven't seen too many GMs in game though.
is probably second place, good ideas, not so great implementation. Still needs work. Most players are on PvP and I have never seen anyone on the PvE server. But definitely not a bad look. Staff seems to be active, haven't confirmed that. I think I've only seen 2 GMs in game....
There really isn't a third place since all of the other servers are basically the same.
Hope that helps.
