Man I'm still so torn on what I want my Childe team to be. I like him with Ning/Noelle because the earth resonance is surprisingly good, and will be even better after the 1.3 buff. It also prevents him from getting interrupted or knocked back so his damage is very consistent and safe. I've been running Childe/Beidou/Ning/Noelle with him but I just can't sit with that team now that I've seen how good his vaporize procs can be. The natural solution is to slot in Xiangling, but I hate Gouba so much. So much.
I tried Childe/Xiangling/Fischl/Jean, which is pretty good, but no resonance and no claymore for geo shields. I tried Childe/Beidou/Fischl/Jean which is great for energy recharge but has the usual weakness of "no fire character" for shields and igniting stuff and vaporize. I tried Childe/Xiangling/Benny/Beidou which is probably the best universal party out of the ones I've run, but I am not really a fan of Benny's kit after playing with it a few days, and I still really hate Gouba.
My ideal scenario would be if they release a fire Beidou, or any off-field fire support that isn't god damn Gouba. I tried Xinyan with this party, and she's ok, but her kit doesn't really mesh well with non-physical damage types and she likes to be on the field for most of her talents.
