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

[Xirean]

All this talk about G'raha and I'm just sitting over here wondering why Thancred is still here. I've had a problem with him since meeting him in Uldah and the game later on called him one of "my closest friends" in a dream sequence. I've got no issue with people disliking a character. It would be nice if the game had more ability to let people express how they feel about events or individuals. I realize that is difficult given the game's structure, but I honestly don't care. If someone presents a stupid plan I'd like the chance to at least call the plan stupid before we HAVE to do it.

Either this is an "all opinions are valid" situation or it's a "my opinion is the objectively correct one" situation.

That really depends on what the opinion is. Genocide is wrong and if someone thinks it's right, they are wrong and their opinion is wrong.
