Peach is pretty high don't you think? Upper mid is a little big and jumbled up...
Mid is fine but still too big. I'd probably move everybody right of WFT down to low mid.
...Don't get how Roy is ahead of Marth when Marth has better theory and results. Actually I don't think any of them belong in that tier.
Link and Robin seem more low mid then low, IMO.
Palutena's results are way too good for bottom tier, possibly also low mid. Not entirely sure what makes Mii Swordfighter bottom either.
Peach has potential, but her difficulty against campers and zoners can hinder her ability.
There actually is no low mid; it's just low tier.
Have you ever played a roy player? You really underrate roy sometimes.
I can understand marth having better results, but better theory? Ahhhhh, no. If you took the time to play roy you'd see why he isn't as bad as you make him out to be (though to be fair you aren't the only one underrating him (still looking at
@AceStarThe3rd and his huge incompetence)). Also, marth has been about as explored as you can get. He struggles against a plethora of characters like pikachu, sonic, various zoners, etc. Yeah he beats Mario, but even with his buffs, I can't really see hime being solo viable.
However, marth, roy, and lucina have tools that they're just too shy of mid imo, but they're nowhere near low tier (hence the marth n clones tier).
Robin and link are a little too slow for mid imo, though you are right, I do feel that I'm not givin them enough credit.
What results has palutena had recently? I honestly haven't seen them.
The miis are all with their 1111 movesets (I really need to say what movesets they use XP) and all mii players will say how bad they are with their 1111 movesets.
Sorry the mid and upper tiers are too big, I haven't made a tier list in a long while and it felt wrong placing some of these characters into lower tiers.
