Following what said, it could be wise to avoid using protagonist from two round of AT when it could be a classic mascot or enemy IMO. In the case of Min Min / Spring Man, it feels like they are not bothered since they have multiple options on hand that ensures the chance of "character being both NPC and PC" is zero. Fire Emblem is also a case where ATs and fighters could all be protagonists from different gens.
I get that many of the current ATs are series protagonists, and we'd not know if that is a direct deconfirmation of whole franchises. Yuri, if he follows the case of Lyn and Spring Man, it doesnt feel like his franchise can easily nominate other proper candidates people like. As for Golden Sun, not sure if Matthew is an acceptable choice of first GS fighter at this point.
The part I particularly care about is whether Isaac is the majorly acceptable option in this case (I think it's clear GS doesnt have that many options that ARMS could give so it's easy to narrow down the possibilities). So the question would be whether Min Min is a debatable pick, and whether other options beside Isaac are more or less debateable.
I sure can understand why Issac is the ideal choice (if not copying the Cloud case who isn't the protagonist from original title). So as stated, I'm personally supportive of him.
You don't seem to be arguing my point, you just refute the idea that Isaac could be both an Assist Trophy and a fighter while arguing hypotheticals and saying that the team cares deeply about characters not being both PCs and NPCs
when we've given you many examples of that not being true. Even if we ignore Chrom,
who can literally beat himself up, characters like K. Rool, Link, Samus, Captain Falcon, hell,
Isaac, all have Mii Costumes, giving them NPC roles (not to mention the many variations on characters in Spirits, like Kaptain K. Rool, Wedding Mario, etc). It's been asked many,
many times on this board whether we'd be ok with a non-Isaac character, and the general conclusion is, we'd be happy that it's new GS stuff, but it would feel weird for it
not to be Isaac.
I understand being skeptical, not everyone here is as optimistic as I and some others are. However, if you're not going to be arguing in good faith, I ask that you please stop with this argument. You are on a board
specifically for supporting Isaac, who happens to be an Assist Trophy. The
vast majority of us believe that doesn't matter. You may not agree, but your argument against it is flimsy and based on hypotheticals and assumptions about the dev team which have been proven to not be true. I don't want to discourage your participation on the board, the more the merrier, always, but at a point it seems as though you're only trolling or here to argue. I'm almost certain you're not doing either of those things, but if you refuse to engage in our points, then it's not a good argument.
