MMH is broken. I don't think it takes a rocket scientist to figure that out or a high end courtroom to declare it as true. The ridiculous potential of the character was
called out on day one after the final patch.
Broken to me (The FGC term, not the technical term) just means retarded character design, ludicrous special moves, and quite possibly no weakness or completely even rival to the character. I don't look at broken as "OMG NEEDS INSTANT BAN AND 10-0S EVERYONE". Broken is beatable.
Semi-Broken are characters that dominate a large portion of the cast but then lose to some characters.
Bannable is a completely different story. Bannable is what you use to describe characters that 10-0 everyone or are just too strong they cannot lose once you reach a certain level.
You're severely underrated Orbs. They aren't just used for zoning. They bait movement, create set ups, can put you in "do or die" situations, fuel his pressure and rushdown game, set up barricades for guaranteed interactables, bait wake-ups, create unclashable combos, build a ton of meter, cover your ass in many situations, etc. etc.
Now I'm not saying a lot of his other moves aren't ridiculous. Obviously MMH is not a one trick pony. He has access to a plethora of bullshit moves. I'm just saying Orbs are his most underrated asset. I feel like you NEED play as MMH and get to a certain level where you understand and have his "Orb Meta" down to truly comprehend. Too many players don't understand the mindgame and yomi levels of placing a orb on the screen and reading your opponent's movements and reactions. Banking and milking orbs in the neutral situations is fucked up.
