Oh no sorry I forgot to reply xP
As for Dehya, actually not so bad! I've been using her with Ganyu and Ayato. I also pulled for Baizhu and Kaveh and really like the Cyno/Baizhu combo, I think he turned out to be a pretty good healer. Though I haven't been playing Genshin quite as much since the new TCG-themed update isn't as interesting to me (Kirara is adorable though) and honestly I have been distracted by Honkai Star Rail I didn't think I would like the turn-based combat system as much but I think it has grown on me! And the writing is actually really good, lots of hidden jokes/references to other media. It's not open world though so we'll see if it keeps holding my interest in the future when there's less to do.
Nope, my frost units are all A0 xD I'm now taking a break from ToF until 3.0 but most recently I was enjoying my full aberration team with Lin/Fiona/Claudia now that she is in the standard banner and I could get some more copies of her. Good luck on your Rubilia pulls!
