I play a ranger named Aarnon on the Fernia server.
Excellent game overall.
Sometimes its difficult to find a group to quest with, but now that all the kiddies are losing interest because it is not possible to "camp" a spawn, and "ninja looting" is nigh to impossible, I think it will continue to improve.
Yes, those were two of the many reasons I left evercrack years ago.
As to how close to Eberron it is, I think I'd have to say "pretty close".
They massively and extremely nerfed the Warforged, but I can understand why.
And the spell casting would not even remotely remind anyone of D&D.
They way they do stats is definitely D&D, and their levelling system is similar in many ways.
In other words, "Its not your daddys D&D" But IMHO worth checking out.
