Say what you want but in three months when every list starts looking like that hit me up with that @ on the citations page. AP style, double spaced!!
There's no real rhyme or reason to numerous decisions on your tier list, using the excuse of "this'll be what it looks like soon!" or not.
Little Mac is too high for an optimized metagame. I've said since Day 1 that Mac is doomed to be bottom tier because he's one of the most gimp-prone characters in the entire series, and as the meta optimizes, he's only going to get worse due to a lack on an aerial game, lack of projectiles, lack of disjoints, dismantlable comeback mechanic, and appallingly bad recovery. He's living proof that frame data isn't enough to make a character good.
I said that Cloud will get worse based on potential gimpability, but he's not an awful character in 6/7 areas, so Cloud can scoot by with a mediocre recovery since he has a good comeback mechanic, fast attacks, good coverage, etc. I think people might be overating him a little bit, but sure, he has a lot of good potential to be upper-Top 5.
People can argue about how Mac might be "better" than that, but you have him above several reliable projectile-heavy characters who are likely to be at least semi-decent as the meta crawls along. I'd expect a more optimized metagame to have Robin and Toon Link in the upper 50% of the list, to be honest, with WFT hovering nearby. This may be why characters like Duck Hunt Dog see modest success overseas - extremely patient players pushing camping as far as they can.
Roy being above Marth post-patch is just silly. While I initially thought Abadango placing Roy so low was ridiculous, there is a fair assessment that Roy as a character is doomed from the start because he's a character who's intended to be aggressive yet carries 80%+ of Marth's moveset. Marth is a defensive, spacing-heavy character. It would be very difficult to translate that kind of moveset aggressively, especially if all you do is change sweetspot hitboxes.
I mean, there might be a couple of details here that are right, but I gotta say, this is a special snowflake-heavy list with a lot of unreasonable decisions without a lot of logic behind them. It's why you explain your tier lists and the more controversial placements when you post them. I mean, hey - Dedede could really be the worst in the game. I sure think he sucks. But your logic is "He's really bad, ya'll." What does that say? Not much. Zelda's really bad, ya'll. Such insight!
