Been playing for a couple weeks and things are definitely slowing down for me now at ~AR42. Could really use some help figuring out what characters to focus on to make me stronger / build a better team.

I currently run C1 Yanfei (lvl69) C0 Mona (lvl69) C0 Xiangling (lvl69) C0 Chongyun (lvl69). I also have: MC lvl 70, C1 Diona, C1 Beidou, C1 Kaeya, C1 Noelle, C2 Ningguang, C1 Sayu, Barbara, C1 Xinyan, and then Amber/Lisa.

My current plan is to raise Diona and set up either a melt or freeze comp to carry me through the month until I can pull for guaranteed Baal. Does this sound like a good plan or would I be better served raising Beidou to pair with Baal / Xiangling / X after 2.1? Are there other viable comps I'm missing that I have available right now?

Thanks in advance for any help!
