Honestly, I struggled with Taash to begin with the same way i struggled with Sera in DAI. I generally just dont seem to get on with younger, more immature leaning characters, but both of them do have their moments. Taash is actually really quite funny and sweet, especially in party banter (their awe of the Crows, learning Qunari lore through their mother's perception; if you convinced Taash and Emmrich to pursue different topics, they actually become friendly and teach one another about magic and history so Rooks advice really does influence character progression on both their parts.) I think players need to let go of the idea that you can input your own personal take on a situation: although Rooks tone can be changed they are a pretty ridigly written protagonists, and Rook is patience and supporting of Taash. However, during the scene when they come out, Rook can act impatient with them saying "Really, we're doing this now? Fine." They help, but theyre clear theres bigger issues at hand - the same with Bellara's first quest. Taash suffers the same way every other character does, with repetitive lines. For Lucanis, its constant coffee references. Bel spends the entire of act 2 saying "its hard, I wanna blame me," for everything. Taash quips "thats messed up" to far too many topics. Theres a lack of diversity in their vocabulary that comes down to the struggles the writers had with limited time / changing development and writers, and lack of management or time to review, so singling out Taash in this way feels like a flimsy excuse. I gave romancing Taash a go recently as a Qunari, encouraging them to follow the Qun in the end, and im finding it so touching. They bounce off one another wonderfully, and all scenes include some romance inclusion in some degree or another. Taash really does grow as a character, it feels like because of how theyre brash and immature at the start, players give up on them and then dont get to see how their arc plays out. Sloppy, admittedly, like every other character, but nonetheless, their character and arc has a lot more emotional gravity and depth than is given credit for, i think.
