How many hat tier lists do we have?
Dang whatever
Diddy's ability also isn't that bad. If you do a single shot like I see some Diddy's do, it can help you from getting caught in a situation where they banana lock you.
Also Sheik's needles are godly. Sheik is a surprising campy character and if full charged needles deal 18% I dont see why you wouldn't camp. Therefore take this awesome ability for yourself. Samus and ROB same story.
There are actually a lot of things you can do to make your list better. Be more specific b/c things like pretty useless, useful, and should be obtained are kinda vague, and you don't even list all the moves.
