Amen to this.
Honestly, the way Wuk Lamat forcefully stays front and center in this story seems like a pointed offensive against player mindsets. It's like they are attempting to smash people's conception that the WoL is the main character of FFXIV by giving us this NPC who has the mask of being a main character, but none of what actually sells a main character.
Like her leaping into the fight to help WoL is practially a countdown to ending the fight, as much damage as she's doing/buffing the WoL to do, and it happens in the latter half of the fight... When Sphene was already on a back foot.
But I guess this trend of the WoL, "needing help" started back in Shadowbringers, and Shadowbringers was so successful they've sought to copy it twice now with how end trial fights resolve. Azem Stone into 8 man WoL team into villain nearly beats them with his big attack, into the WoL getting hypercharged by powers outside of the fight.
In Hades's fight, it was the Lightwarden light combining with The Blessing Light to both shield and increase damage from the WoL team. In Endwalker it's the Prayer bubble from the Scions that save WoL from Meteion's death surge of Dynamis. In Dawntrail... WoL is beating Sphene like a redheaded stepchild, and Wuk Lamat steps in anyway, super buffed, super buffing WoL and it goes from a murder to, "Stop, stop, she's already dead!"
