I disagree because the premise of this crt is trying to equate anyone's love to a full pure hearts level amp which is wrong. The pure hearts are very clearly special items created by the ancients that are directly stated to
amplify love energy with them even seeing the power of love from the pure hearts to be infinite.
The basic concept of love sure, bonds would include that, but this shouldn't include what the pure hearts do, which again, they are a unique item that
amplifies said energy
to do things far beyond what brothership shows.
The Ancients creating the Pure Hearts
from their love is a unique thing that can't be replicated, with them even going out of their way
to research this power in order to harness and
amplify them for
power with them. No other character in SPM when displaying love, even during Bleck and Tippi's wedding, causes anything like the Pure Hearts to be made. Bonds don't draw out anything like that and should be very noted that they are
ONLY an amp when
poured onto characters with a unique item: the
bonding can. Equating everyone's love feelings to the power of pure hearts undermines the entire purpose of the macguffin existing and the lore behind their creation involving the ancients.
This is also why i disagree with all of DDMs examples as well which i have a feeling would be used as an excuse to argue for higher tiered feats that I do agree they should scale to a multitude of, but I do not think this is the way to scale them to it. Power of bonds love friendship and whatnot is a thing throughout the games and is a general trope in fiction, but is it literally NEVER treated as an amp at all, especially not in the way brothership does which i again will repeat is uniquely done via an ITEM that has to directly collect and be filled with bond energy and then be poured onto the bros. Mario having a desire to save who he loves, or working alongside luigi would NOT be an amp they get, nor is it ever treated as so. stuff like peach and wishing is situational because star spirits whole job is granting wishes and they decided to use those wishes to amp themselves. The rest of the examples are just "characters can sometimes stronger attacks with this". Bowsers minions legitimately can just scale to the main cast at times depending on the game, though fodder enemies
especially in hordes can sometimes ignore tier division that a scalers would see within the media itself since the creators dont see it in the same literal way we would interpret it in a scaling sense.
The elite trio boss fight is a good example of this in mario itself. This is also more notable in comics covering game franchises where fodder hazards and enemies can sometimes
deal damage to the mc that we would normally dismiss as game mechanics within the game itself.
