Just genshin stuff

The 4⭐ are the most underrated from my opinion actually,think about it. Kaeya for example, he is pretty cool, and an amazing personality is shown in-game and even in the comics!!! But (most) people I talked to are always sayin bad things about Kaeya for being one of the basic characters, and as a Kaeya (player) that hurts. Sucrose, although I don't know much about her as a character because I haven't gotten her from the Klee banner, she is also very underrated- I haven't gotten to see or know anything about that cute little one. Xinyan is also one of these underrated characters, people really don't like her for some reason, is it because of her English voice actor or? Please to me whats bad about those characters.And wich characters in Genshin impact do you think are underrated?
