I don't have the feats working quite yet (I thought it was all well and done as of last night) so I wouldn't bother taking levels in the class yet, as you will basically be taking gimped rogue levels.
Details about the class, its function, etc. will be released when I get it working all the way (hopefully later tonight, but it's difficult because every time I change something I have to restart the server to see if that change actually got reflected correctly).
In the mean time, consider it in beta testing.
