WOMANpukumaru I took it for being just the first version of this route, and that more things will be added later. I mean, this is not even the real update but the bughunt?
That said, you make good points (but we need to keep in mind, as we both said, this is just the first version).
The Korra stuff seems to get her trust too easily and most of it is through her exposition. Sure, we are her future life so it is easier, but still.
But we are given some extra characters but besides Kya's and Katara's scenes not much do do with them yet. Even just hints of any plot, Jinora seems to be reverse-Nagatoro, Ikki has self-esteem issues, Opal gives some vibes that had a crush on the possessed dude. Hopefully they will be linked to Korra's plot properly and we can get some more material into them.
Also we don't know how far it will go after Korra's treatment. We may get into some actual show plot, where we meet Asami too.
The minigames to me always felt... exactly that, minigames, so I don't mind them that much.
It is kinda weird that the treatment minigame and the windbender one is the same though. I kinda expected after the first Tenzin and Shady scenes that Tenzin would not be considered a good teacher and Shady was the real training, I mean at least it involves some airbending... but when Jinora takes over she does the same minigame and your character acts like her training is being good now.
Eh, my main draw to this route is you actually being you, want to se how them both being Avatars but of different points will affect things. Hopefully she finds out mid-story so some of the plot is affected by it - maybe just not enough to change the future he was born at... but again this is the very last canon place, so why would it shy from changing the future, nothing that big to preserve of canon and we don't know the MC's canon past save that Aang and Korra until this point happened there... and not that big into Korra, because...
Saraf it is almost certain that either FET will either fix or imply it fixes itself over time, maybe even fixing it will be the plot of Book 5?
We do meet and have scenes with two past Avatars through the Slave Route, and
not through Korra since she is unaware and not even close by most of the time. And
we are the one to enter the Avatar State with others through our spirit, fixing Korra for her though our cown connection. As I read once the loss of the connection to the past lives also removed the connecting to future ones this should only have been possible unless it had been fixed at some point.
