i feel as if i'm too panic-y with my button mashing! like, i'm doing a lot of work and not seeing a high hit percentage. (it doesn't really help that i'm maining ness, who is pretty button-mashy in the first place with djcs and such haha.) do you guys have any tips on slowing down and playing smarter, not harder?
Ness is very limited in his ability to attack while moving forward. Most of your hits are going to come from zoning good hitboxes like fair and bair or punishing people who overcommit (dash away, DJC back towards them and bair). Pressing a lot of buttons isn't necessarily bad as long as you aren't doing extraneous inputs, and slowing down is not equivalent to playing smarter. Ultimately, you need to be playing as fast as possible and still make good decisions. Start out by trying to make good decisions, and once you find yourself picking good options that still aren't working, you can try to improve your speed and efficiency with those options to make them more effective.
If you just need a single word to reiterate all of this to yourself before every match, it should be "positioning". Always focus on your position relative to the opponent. Here are some good questions to ask yourself:
Which of us is in a better position?
How can I change from a disadvantaged positioning to an advantaged one? (This is why people roll away from the ledge so often.)
How can I beat him from my disadvantaged position? (This is why people charge with a "desperation" attack from the ledge.)
How can I abuse him with my advantaged position? (Waiting and attacking on reaction is very powerful when you have stage control.)
