This is some D&D wiki stuff.

Way OP, and doesn't follow the design structure of Rogue subclasses at all. It does nothing other than adding damage or AC, which is not at all what a Rogue is supposed to be about - even your most combat oriented of other Rogue subclasses add some kind of skills based feature somewhere.

Every feature is some excellent damage or defensive boost, and two of them increase massively at higher levels - that's too much extra power. What's more, the AC boost feature is poorly worded in such a way that it can combo with the (insane) double bonus action attacks to make your AC stack to obscene levels. The Parry feature has way too many uses and no action economy cost - at many tables, this would be used every single attack made against the Rogue, given the typical shortness and frequency of combats most of the time.
