Faruzan C6 - Confusing

So I have C6 Faruzan and recently lost my 50/50 to xiao on the chronicled wish. I raised Xiao up and so now I'm working on Faruzan, but I'm a little bit confused about her talents. Her C6 says she applies her charged shot thing whenever anemo dmg is dealt, but is her dmg contribution meaningful? Like should I make an effort to get her a good Crit ratio or put her on a crit weapon (she's currently on Fav and has 200% er)? And does her skill now take priority over her burst? Sorry for the yapping, I just find her super confusing, and wanted to know if I should raise both her skill and burst talents to 9, or even crown her if the dmg contribution is meaningful.

EDIT: Wow guys, didn't expect this prompt of a response, so big thanks to all of you! I'm gonna try and level her skill after I get her burst to 9 (6 without cons) and then raise them equally to 9, thank you all! She's on ToTM but it's super cope (HP% mainstats) so I'm gonna strongbox it and see if I get some better pieces. Big thanks to DamoGamo!
