I've been messing around with Dash Attack a lot lately. I find it good for punishing landings in certain situations, but I'm not sure how useful it is overall. Oh! And there's a way to Dash Attack faster, for those that don't know. If you just normally dash and then press A, you have to wait a few frames, because you won't be able to dash attack in the take off animation for a Dash. Instead, you'll do a Stutter Step Forward Smash. However, if you hit down on the C-Stick, you can Dash Attack during the initial dash animation, cutting a few frames off. Sometimes I'll dash away from my opponent, pluck cancel my dash and Dash Attack the opposite direction towards the oppponent.
