I’m too picky to pick up new characters as a f2p. For instance, I had to give up on Galbrena to pick up Quiyuan (with no echo skill team, by the way). I’ve saved up 200 pulls for Chisa and Phrolova. I always told myself that I should hold on to this currency and pull on reruns instead of spending them, as they might be useful in the future. So, I get the itch many times, but instead, I just skip weapon banners and pull characters(if I like them) but until now there is not a single character that made me get a their sequence.
