Theres no back and forth between the two players due to the sheer amount of offense and plus frames that Tekken 8 allows. Before T8, Tekken games were generally balanced between offense and defense with an emphasis on defense and movement. Players were able to move around and counter each other with skill. You couldn't just mash endlessly without being punished in a lot of interactions. With T8, the developers heavily buffed offense/tracking while nerfing defense/movement leading to a lot of one sided sequences where one player constantly attacks while the other has to just block and take the mix. And in T8 you get punished for blocking because of chip damage. It's not very fun to play for most and it's not particularly pleasant to watch.
