guy above me is wrong ninjitzu is good for pvp.
Fast recharging heal, blinding powder to get someone off your tail, if you wanna build defense just worry abut range and try to get it to 60% it will DR down to about 40ish which is noticeable especially for peeps that don't work accuracy bonuses in. Plus it has retsu a clone of elude which is also sweet just pay attention to when it crashes so you can duck out and rest.
oh ya it's got a kb hole may wanna do something about that almost forgot.
edit forgot: which powers to skip
caltrops ok for no brain enemys, less then useless for a stalker against real peeps.
smoke flash i think is useless too, to small radius but that might be just me idk.
everything else I would take.
