From the beginning... interesting that he goes for flair rather than charging anything. Playing Wii Fit Trainer already awards maximum style points. And around 0:25, he goes for a dud f-throw that gets counterattacked, rather than throwing up or down for big damage. Around 1:45 he gets one of Wii Fit's golden combos but... randomly gives up on it? He goes for lots of dash attacks for long-range approaches, when pivot-canceled tilts would be MUCH more effective. Perfect opportunity for a Header sweetspot at 2:40, forgone. At 3 minutes, he uses another dud f-throw instead of a combo throw--he wanted to get his opponent offstage but didn't even chase OR charge up. He could've gotten the best of both worlds from up-throw -> f-air. Instead he did literally nothing.
That's my analysis of the first match on there. He's not taking advantage of combos, and not making good use of time. Wii Fit Trainer should NEVER be standing around waiting. If you're not charging, you're breathing. If you're not breathing, you're setting up a Header angle. He got really lucky on that last stock.
In the same way that I can't stand watching a Villager player who doesn't know how to do anything but spam slingshots, I don't like watching WFT players who treat her like a normal character. She's extremely abnormal--that's why nobody plays her. She's not good if you try using standard/generic strategies. At least he wasn't trying to go for b-airs in neutral at low damage, which is basically my ultimate trigger. Compared to n-air it has worse range, active frames, vulnerability, damage, combos... and yet people STILL try it.
