I learned quite quickly that people don't care ONLY about the potential. If they were, I wouldn't think he Paper Mario case would be annoying to manage because of the another mario argument. I actually learned that this is based on repping logic, not movesets and even weirder, the clone belief is actually not that popular.
So, trust me, they do think about other things than movesets.
However, I will agree on one thing, I often realise people take moveset....in a weird way. Because a character is an abstraction, that character is theorically endless possibility. The ONLY thing is that the moves would have to make sense and go in one direction being the playstyle, but the playstyle is an abstraction, an interpretation if you want meaning it's not fixed. So, if I read for example that "captain toad can't jump", I ask myself "why it matters SO MUCH?". I mean we saw a ton of example where the character didn't do a move like he does canon (the best example is c falcon). This is because the moves are abstracted, they might not even exist, but as long as they go in one driection that is meaningful, it's fine.
So, if he can't jump, why not just putting a LOW jump and a porr double one?
Or, why not having some animations that will make sense to have more height?
See? It's just design details. I agree that the subset dictates how far you can go in potential, but you realy have to have a very undevelopped subset to not be able to have a whole playstyle. Sometimes, it might just be due to the subset not being consistent, but I hoenstly think these cases are quite rare.
Which is why the potential in the end....doesn't matter the most and might be something that matters not much because you have a lot of different factors to consider before. If a character however satisfy pretty much everything, THEN moveset matters because if the character has a unique subset, the playstyle SHOULD be unique too. This is qhen you check how far you can go.
I honestly think the moveset is the last factor to check a character. I first check the subset, the importance of the subset, the possible delegate and if the character is a good one for his subset, how deep his repping would be, how maintained it is recently. Then I check quite the uniqueness and how would it contrivute to the diversity of the roster and by how much. THEN, I check the playstyle and movesets.
it's just logical. If I was considering movesets before for say shovel knight, it would be a bit weird, because he has lots of potential, but his addition isn't worth much int he first place considering several factors and the main one being third party indie....this requires quite huge standard if i check who managed to get in as third party.
It's funny how counterarguing about Paper Mario made me learn how people think about every characters
