Apologies if this has been mentioned already, but I think going over our WoL's role in DT, the thing I possibly get the most frustrated over is that we are referred to as her Mentor a few times, but never did I ever actually feel like her mentor (apart from maybe 2 small times I can think of where I was allowed to cross my arms and stare at her disapprovingly lol). Considering the wide breadth of nations and experiences we've had from ARR to DT, I think it's a huge missed opportunity that we couldn't have more actively instructed her, as a mentor, in our past experiences with other nations and leaders, and how some of those stories could've served as lessons for her on either what went right or what went wrong.
There have been many times in other expansions where we've waxed nostalgic on moments from our past; there could've been some nice moments where we could give her flashbacks as to important times where we dealt with a similar enemy, or felt a similar way towards a government or situation... we certainly have enough experiences dealing with tumultuous nations and their leaders. Then, she could ask questions about those moments, and start to gain a better understanding outside of her initial childlike "I want everyone to be happy" mindset of how that's not that simple and how to think critically about topics in a more realistic, sophisticated way. If she can't be worldly since she's barely seen the world for herself, then it should've been on our shoulders as her Mentor to teach her about those worldly moments that WE experienced.
Also, in the fight with Bakool Ja Ja, she pretty clearly uses Dynamis, as she's able to solo LB several times in the fight, but the narrative doesn't really tell us how she either trained or advanced herself to do so. I guess it could be just from the rage from her birth father being held hostage, but then there's other times where she rages and she's nowhere near as powerful. It would've been far more satisfying if the WoL could've had some sort of gameplay moment during their travels where the WoL could've imparted to Wuk what they learned about the power of Dynamis from their EW adventures, and the Wuk in turn learns from this and levels herself up with our teachings. Then think how satisfying that would be to have the game reveal she could LB on her own in the fight thanks to us, while we look on behind her, arms crossed with a smug grin on our faces.
I just feel that this was a huge missed opportunity in letting the WoL have an active contribution on this new character. I think people would've felt more connected and less like the tag-along character that we ended up being. Rather than a true Mentor, we just ended up being a weird sort of bodyguard/gofer attendant who functionally was way too much of a crutch for someone who really needed to learn things the hard way but ultimately didn't.
