Personally , i think saki is not that much of a priority. I'd rather raise bashira , since archers are more general use. After that i would probably cc bernice , since a secondary tank is always good to have. Celia is a very good duelist as well , since she has a massive hp pool , MR , decent damage and a skill that reduces damage as well. It just depends on what you want to do with your team. Other then that , i kinda agree with sora
