I hate this new system because you don't have much control over what you do immediately after SE.
Like in SC3, SC4, VF4, and VF5... you could choose if you wanted to stand guard or crouch guard after an SE. To stand guard after SE, do SE by holding Guard and mashing 46464646. To crouch guard after SE, do SE by holding Guard and mashing 13131313.
Now that you have to do circles to SE in DOA5U... you're literally playing roulette with where you are going to be guarding after doing SE. SO MANY TIMES I have gotten caught by stuff I knew was coming after SE because I was unable to immediately crouch after SE due to this terrible system.
Also, because I want to come out of SE guarding, I hold F during my SE input, which tends to lead to unintentional Hold attempts, which tends to lead to me getting HCTed when I didn't even want to do a Hold in the first place.... -_-
