Right now I have a lonx bg and wanted to know if I should get ferren and nohkan champs from poxbox to make a bg.
Ferren as a theme is non existent. They had an OP racial and got removed without anything to replace it. Thankfully revising themes is high priority now for Soko (lead developer). About Nohkan Do, most ST players I know doesn't like it's mechanic. Find it unentertaining to play with, and on top, other faction players find it unfair to play against (despite all evidences shown to them that it is not as powerful as it looks on paper). Despite all said, in low ranked leagues (exo, rare, unc) it seems like you can play anything, have fun with anything and win with almost anything.
