The biggest thing that stands out to me, outside of
being really low, on this one is
. I've never found his theory that great (Having no air game and a problem getting around shields, for instance) and he seems really easy to gimp. Do people just keep running into smashes or something?
the last sentence triggers me deeply
facts:
1) LittleMac has one of the best "defenses" in the game (NOT TO BE MISTAKEN as disadvantaged state, that one is pretty terrible), his awesome frame data is beefed up even more by the properties of most of his attacks
tilts (and jab) have the "trample property", meaning that they cannot clank with other hitboxes, so he won't suffer in extra lag when dealing with projectile clanking or when stuffing out other attacks
his uptilt is basically a big hitbox that doubles as a shield of sorts
his smashes have super armor (well this is pretty obvious but still-), meaning you can't be liberal in throwing attacks out
he also has a great traction so he won't be pushed away when you hit his shield, and his OOS option are pretty good:
f8 jab, f10dtilt, f11 ftilt and f4 upb (3+1 jumpsquat, also with invincibility on his startup) (his grab has pretty poor range and will probably miss even with his good traction)
having to approach a Mac with the lead is no easy task for a lot of the cast, actually
2) "he seems really easy to gimp", he is easier to gimp COMPARED to the rest of the cast, but this does NOT mean that everytime he goes offstage he will die, just go look at some good LittleMacs matches and notice just how many time they make it back onstage, the gimps are not that commonplace
It's true that the distance he can cover while recovering is abysmal, but he CAN mix up his recovery in lots of ways that most characters cannot cover with a single option (I already wrote a pretty detailed post in the past and tbh I can't be arsed to search for it, let alone rewrite it, sorry for that)
3) "problem getting around shields", this one is more matchup dependant
Mac has dtilt (-5 on shield drop) and down angled fsmash (-6 on shield drop and TONS of pushback)
characters with bad or short ranged oos options have a really hard time dealing with these moves
when Mac hits your shield you're put in a "frametrap" situation, if you drop your shield and throw out an attack (or jump) you will probably be hit by another downtilt/jab/something, if you roll away you lose your stage control (important against Mac) and can also be read and punished (spoiler: sideB is a great move for punishing stuff) and if you hold your shield you are putting yourself at risk of getting shield poked or worse (down angled fsmash destroys like over 60% of a shields health, add some previous dammage from dtilts and stuff and you are seriously at risk of a shield break)
also, making the opponent rely on his shield a lot opens mixup situations with his (usually bad) grab (and Mac's pummel + throws deal quite a bit of %)
LittleMac is a lot deeper as a character than most people think
(sorry but I'm kind of tired so I'll stop here)
