Daisy and K.Rool are just so uninteresting to me and gameplay of them hasn't changed my mind. Daisy has been one of my most hated characters ever since I played MKWii.
K.Rool is someone I just don't care about as a character and his fanbase was probably the most annoyingly toxic people I've seen after Smash 4 released.
And as a fighter? His moveset feels completely uninspired, specially his specials: koopa cannon+inhale, ROB's recivery with a hitbox, a boomerang that sucks and a damn counter. His A moves are just as basic as the Smash 64 characters
The original echo fighter is ironically the least echo fighter-like echo in the game... go figure.
Try saying that 10 times fast.
Ironically, he's less of an Echo than the Melee clone trio of Dr. Mario, Yink and Pichu, who all, at most, have two totally different moves from their original counterparts.
