I apologize for my initial reply, @
Alacion
! I will make a proper reply this time around.
Of course, I read the whole tier list. Personally, I have to say I disagree with most of the placements, including Bowser's. He remains a large target and I strongly believe Peach and many other characters will maintain an advantageous match-up against him.
Only the "F-Tier" (bottom) appears to be more plausible, but I'm pretty sure I am wrong! Mega Man, based from the demo, appears to be a fighter with very limited options and his projectiles are completely walled by Link. Ganondorf seems to be relatively unchanged from Brawl and Falco appears to have received significant nerfs to justify this placement.
There are also other things affecting the tier list, like starter stages, counterpicks and above all else,
custom moves. Plus, there are also many skilled players who did not touch the full game yet. Amsa, for example, showed how good of a character Yoshi could be in Melee.
