Your arguments are bad and you should feel bad.
If Daisy is so cool and strong like her fans say, she would have another role, not just a damsel in distress, like Rosalina.
Also, did you seriously say that Luigi would be like Daisy without the two players option in Mario games? Luigi's Mansion says hi.
Toad is more important to the Mario series than Daisy, that's why Toads are playable in the main games, that's why Nintendo created Captain Toad and the Toad brigade and that's why Toad is the only Mario character not in Smash that has an amiibo at the moment.
You saying that Toad doesn't have moveset potential is funny, because Daisy has even less, all the Daisy movesets are lame, they just include random sports things, even when literally all the Mario characters like sports, seriously, the movesets include that Crystal Smash thing from Mario Strikers, that's so random it hurts, I don't see Peach growing wings and attacking with soccer balls in Smash. The other movesets include some flower abilities because Daisy, well, I say Toad has mushroom abilities, GG.
Daisy is just a filler character in spin-offs, even characters like Toadette or Birdo make more sense because they have roles in not spin-off games, like the RPG Mario games, Captain Rainbow and Captain Toad: Treasure Tracker.
Supporters like you are the the reason why Daisy is so hated.
Pure bias and ignorance.
