I think they have made attempts to show the acrobatic Ahsoka, it's just harder to do in live action. In nearly every fight they have had her do something "acrobatic". I think they are absolutely emphasizing that Baylan is REALLY good, so good Ahsoka is at least evenly matched. I think they are building to some dramatic way Ahsola beats him from a narrative standpoint, or that someone else beats him. He's definitely being built up from some shocking moment because they have made him Dooku level good.
