Several months ago I was playing a dual-wielding character who used swords. Whenever I did a left-handed power attack while moving forward, it would be pretty much guaranteed to stagger the enemy for a second. The left-handed forward PA is slower than the right-handed forward PA, and so is easier to 'aim'. It was a nice feature, and I used it a lot.
Now, for some reason I can't pull off that move. I mean, I can do a left-handed forward PA, but it doesn't stagger.
Has something changed with the recent patches? I'm running with no mods whatsoever. Or am I just doing it wrong now?
