2000 cunning is obtained in one way that I know of. First off, Battlemaster gear =/= Rakata gear, at all. You may think the ratings are the same, but the stats aren't even close.
It requires all the datacrons for Endurance, Cunning, and even Aim.
It requires full Rakata gear. NOT Battlemaster.
It also requires a Rakata skill stim and Force Valor.
These are the only requirements to hit those vague numbers. Also, the surge rating is a bit too high. You can only hit that with an adrenal if you are lucky.
