I kind of agree with that (@ Beta)

Before you spend 3 turns charging an attack, realize that the other person---provided they have a decent head on their shoulders---will probably observe their surroundings and the nature of the attack, and react accordingly. If anything, you need to use attacks like those sparingly and with some tactics backing them. I'd use them heavily in tag-team matches, where my partner could set up a foe for such an attack by disabling their capacity to move somehow, but not in 1v1s. 

That'll just get you killed if anything.
