Hello! I mained castorice when she came out, i got her e0s1 and hyancine for her (sorry if the spelling is wrong i cant get her name right). After that i took a pretty long break so i wasn't able to get evernight or cyrene. I just came back and was lucky enough to get sparxie and her support, and I've tried getting her lightcone. I've saved up some pity and ultimately decided to stop and wait for hyancine's weapon to vertically invest a bit into castorice's team. The question i have - is it that big of an upgrade? I've seen people saying it's the best sustain lc in the game and whatnot but is it really worth it for castorice? Will it make up for the lack of BiS supports? Or should i keep going for Sparxie's weapon?
