I feel you. I dislike most of the pyro characters honestly! and also, oof, Thoma requires ascension materials from a special huge questline island in Inazuma. he’s kind of a pain to level. the pyro four star I like the most is a tie between Gaming and Yanfei. Yoimiya is my favorite 5 star one, and she works well with Thoma, actually.
you can probably guess who some of my favorites are based on profile pic and banner (eventually, anyway, they’re both in Inazuma.)
who do you have your eyes on that you want, anyone besides Diluc and Shenhe? I don’t know what the banners are currently.
