many suggestions have been made but it continues to be nerfed because there are about three really great moves (spread over the entire spy tree).... and spy almost by definition cannot work properly in a non-hostile environment (if you know when and where hes comming from its kinda redundant). That said there is much to enjoy and as long as you dont mind crossing assassin/mkt/MS there is a decent build or two to be had (in isolation the individual branches dont work well like the soldier tree does).....good to see you back btw
