Yes, because the mobs in this game should totally have the same abilities, because it is about them, not you. It doesn’t matter how your own block behaves. Besides, how about them being able to attack chain and block at the same time? Can I do that, too? No? Then your points is rather invalid.
Designing something to be annoying is bad design in itself and requires 0 effort and consideration, so again, a rather moot point. To craft a hyperbole, if my intention was to design an enemy that party whipes anytime it spawned, I could put that in the game. If it did what it was supposed to do, would it be good design?
Doesn’t matter if you ever had problems with it, it clearly and explicitly states in the beta patch notes that they are not behaving as they should.
It would at least be more logical if they made their shields larger to actually cover their faces and shield-hand side. It would be nice if I could circle them to their weapon hand side, exposing myself to danger but at least getting an opening myself. The large block angle is counter-intuitive simply because the player is presented many openings on the enemy without the ability to exploit them. Their “backside” is smaller than it seems and only seems to cover a 90° angle, anything above that is considered the side and they can block that.
Amazing to what extent people spite logic in order to defend ill-designed mechanics just to uphold their “better than thou”.
