What's the point with that quite lackluster story in Endwalker?

[Midareyukki]

Not going to lie - I get the impression this is fundamentally a lot of peoples' problem with G'raha, and most everything else is looking for more reasonable-sounding justification after the fact. I mean, you don't need it, folks. You are totally entitled to dislike G'raha based on his personality, appearance, and mannerisms. It's just not reflective of hypocrisy or flawed writing or much else beyond "it doesn't appeal to my tastes." Which you are free to say!

On one hand, everyone's a critic.

On the other hand, when your character breaks established lore, pushes boundaries even in fiction with nary any consequence and is consistently portrayed as a loveable bean who can do no wrong other than "tries too hard", that's not really a well-written character. That's a Mary Sue.

Because let's not kid ourselves, most of the Scions are flat, and it's not like FF14 has a story meant for anything majorly deep. But at least:
- Thancred had his Minfilia obssession
- Urianger had his underhanded shady methods that made people question his credibility and loyalty
- Alphinaud had all of Post-ARR
- Alisaie had her passivity and later extreme impulsivity
- ARR and HSW pre-character development Estinien

Now, what flaws do G'raha and Y'shtola have?
- G'raha works himself to exhaustion and bleeds just to please his heroes, but it all worked out fine anyway
- Y'shtola's penchant for using spells that should have killed her but haven't

At least recognize the game's flaws when they're this glaring. Tastes are one thing. I prefer Red Alphi to Blue Alphi, for example. And I do think G'raha is cool, love it when he takes leadership. We all have biases. But that's not really denying poor writing or at least poor character structure.

Unless, of course, you're one of those people who think bad writing is still subjective and Mary Sue-esque characters are perfectly fine. In which case, there's no argument to be made there, you'll settle for anything.
