Duals are impossible unless you're god-tier

As the title says; you will get completely outplayed time and time again if you aren't a top tier player in duals. Every time I play duals, I get parried CONSTANTLY, no matter what I do; I feint a heavy info a zone? Parried. Random light attack? Parried. Random zone? (Orochi, PK, warden) Parried. I'm baffled; how is it even possible to consistently parry the fastest attacks in the game?
