I am so freaking bored of Shadowbringer's story

Please enlighten me how the Nu Mou are important to the story.

Finding the "keys" to Titania.

There's that, and then there's the matter of them having ties to the tank story's Sin Eater, which in turn has ties to one of the local area's A rank hunts. World building is important.
If I'm not mistaken weren't they also planned to be one of the beast tribes we'll deal with? So an early introduction there would be important as well.

Nu Mou and Pixies are indeed two of the beast tribes, Dwarves being the third and most likely the craft/gather one. On top of this the Amaro are shown to be on close terms with the Nu Mou meaning we'll also be getting more of them in the Nu Mou beast tribe story as well.

On the "repetitiveness" of defeating the Lightwardens, even that serves a story purpose - because it's just when you're settled into that routine that you absorb the fourth and you get that horrendous cracking sound as your soul struggles to bear it...

(It reminds me extremely strongly of Shadow of the Colossus which had the same "repetitive" cycle of defeating each colossus and absorbing its essence. The sequence never changed, but my sense of dread got higher each time it happened.)

I think it seems more likely that the Dwarves would be a battle tribe and either Pixies or Nu Mou as the crafters, otherwise we have two tribes doing the same sort of activities in the same zone. And there are plenty of reasons for the Dwarves to go looking for a fight or be under attack from the Goggs.
