In any case Endwalker still falls short of the expectations anyone would otherwise have for the sort of story it presented itself as having, and this cast of protagonists isn't helping much
Thats your opinion alone, and is not one shared by many.

Especially now that the teasing of new characters and storylines hasn't led to much, my anticipation for the future main story is at an all time low. They should know better than to say such things without having any intention of following through with it.
Wouldnt it make sense for you to wait and see what 6.2 brings?

Yes..yes it would.
