The problem with sub isn't that it's not WoD sub (much to shoegazing's chagrin I'm sure) it's that they didn't commit one way or the other (same with outlaw).
Instead of going full naruto ninja nonsense, they decided to do some strange half and half where they kept the absolute bare bones of sub (eviscerate goes brrrr) and replaced the flesh with some half-assed ninja skin.
That and because sub was good on one fight in the first tier they decided to nuke the spec for an entire expansion.
