Blade & Soul private server?
The only client available is the first closed beta one with race/class restrictions and maps and content restricted for level 20 max, isn't better wait the next closed beta phase (maybe the last one before obt) the next month?
They will unlock more race/classes, more content, owpvp, and the assassin class.
Make no sence play now with the client in korean language and all these limitations. Imo.
ps: I think a Tera private server will be much better. Tera is released and complete in korea.
