The green highligthed characters are those who I already have, I wrote the constellations here in case the next constellation of one of these characters was really worthy activating/ if getting c1 was worthy. And if someone says "don't care about meta, just pick a character who you like" there's no character here I would be dreaming about getting and these are 4 stars so I can always get them by pulling on some limited banners. Also while I am kind of picky and liking the character matters a lot to me, if it was a really useful character but I would not really like them , I would live if I pulled for them and strenght matters to me too because I suck at building characters and I can't make a not very strong character do 10k damage like some people, and I used to struggle with a lot of bosses and it was terrible so I don't want this again. In terms of teams, my dps/sub dps characters are Arlecchino, Kequing, Furina. (In case if any of these characters would really fit with any of mine).
Which one would be the best choice?
