Using the WOL to win the support of the xaela tribes was as you say beneficial to the WOL because it allowed the far east to draw attention away from Ala mhigo. As it stands right now the WOL has absolutely zero stake in this conflict. The dialogue of the WOL also shows that they continue to grow tired of being used as a mindless weapon for the leaders of the world so it’ll definitely be important to the story as to whether this conflict actually draws the WOL in in a meaningful way
Right now we only have Wuk’s assurance that one of the other competitors wants to invade the 3 great continents but that could simply be used as a hook to draw in the scions
Actually meaningfully engaging with the WOL as a sentiment human is I think something the game needs to focus on going forward
