I'm working my way through playing two matches with every Smash Ultimate character online, and I'm basically done with the Melee roster and their echoes. I doubt it's just me, but it feels like it - I don't see what's so good about Marth, Roy, and their clones.
They have no horizontal recovery at all (and Chrom's vertical recovery is basically an instant death if you don't know exactly how far it will go), low stamina (I consistently die around 94 or 95%, compared to about 120 to 150% for other characters), the counter seems to require frame-perfect timing, and their side-B seems nearly useless. They have no ranged attacks, and the lack of a horizontal recovery leads to a lack of horizontal mobility. I just don't see the appeal, and I'm hoping that someone can explain why they're so good.
