On the fence about Castorice

So here's the deal. As per the title, I'm debating whether or not I want to pull for the death elf when she releases next patch. Not because I don't like her or don't think she's cool; she's probably the most visually stunning (in my opinion) character since Jingliu, and she looks like quite a lot of fun.

What I'm trying to decide is whether or not she'd be worth it for my account.

Currently, I have:

• FUA Team: Feixiao, Robin, Moze/March (sustain depends on the boss; I don't have Aventurine)
• Superbreak Team: Himeko, HMC, Fugue, Gallagher
• Jingliu team with Bronya & Pela (borrowing Robin when not using the FUA team)

Potential buffs notwithstanding (I don't think Hoyo has given us any further information regarding how, or even when, they intend to start doing it), Feixiao is the only "meta" DPS I have.

But at the same time, already having 3 teams (which I'm still trying to improve b/c relic RNG), I'm not sure how good of an idea it'd be to pull for more new DPS.

So that's where I'd like some opinions/input.

Do y'all think Lethal Rice would be a worthwhile investment? Admittedly, I'd have to cannibalize my Superbreak team so that I can use RMC & Gallagher with her, so I'd have to choose between one or the other when taking on "endgame" content.

But I also realize that the trend of constant powercreep (unless the buffs to old characters are substantial) means that it likely won't be very long before my Feixiao team is the only viable one outside of fire-weak/break content.

So what's the best play here?
