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

[Absimiliard]

No new character will be 'interesting' from the getgo. Absolutely no matter what it will be, the moment new character is introduced as part of 'main group', there will be SOME loud people who will instantly start a bemoaning of how much they hate them and how boring and predictable/annoying and obnoxious/generic and unintereting the new character is and how they cant wait for them to die off to get replaced with a 'more interesting character'. All while in next paragraph complaining about scions always being there and relevant.

No, but there are ways of making a character at least appealing enough at introduction to warrant some investment in where their story arc will go. Enough people dislike Zero that one should at least be willing to entertain the idea SE failed to do this. As well, one should acknowledge the possibility of the direction that character's development has gone in being something more than just a handful of players dislike.

Very seldom do video game characters that stick around for an excessive period of time not wind up overstaying their welcome. You can witness this in action with the myriad of Scion complaints from practically all of the different demographics playing this game. The Scions going their own separate ways after sadbird's defeat gave me a taste of something bitter: hope that SE had realized this. Unfortunately, that hope was dashed in the very next patch.
