weapon help

my team is sandrone, c1 yae, odette, c2 qiqi

basically im in a dilemma about which weapons i should use on those characters, i’ll list my options:

for qiqi im using fav (which iirc is her best but lmk if im wrong)

for sandrone im in between using tidal shadow, the new craftable or one of the battlepass claymores. which would be best and should i get refinements?

for odette i heard that r5 finale of the deep is better and more consistent/versatile then r5 emberwell so i think i’ll use it if it really is better

and finally for yae idk if i should use widsith, the new craftable or any of the battlepass catalysts. again i can get refinements too

any suggestions would be highly appreciated! i really just want to pick the best possible options for my team and maximise my characters. sadly i dont have signatures atm or other 5 star alternatives since my other characters need weapons too lol so i hope the team can still be strong with f2p alternatives 🥹
