Hi i am LowPriority (Also known as LP) i runned a bit of math on her with the stuff i have seen around. [I am not a leaker or have any contact just taking the information i have on the net with a quick search] and i wanted to share my opinion and educated guess on her state rn.

A Fast TLDR. Still suggest or join the DS for more questions

Being a V0 beta furina it's extreamly powerfull, she is an archon in fact, with this said she is not perfect and i expect and hope to see changes in the upcoming weeks of beta.

Energy

First of all i would like to adress the elefant in the room, her ER requriments are not as bad as ppl say they are. Most of this is due to the fact that her ER it's considered in kinda wierd team where she really does not belong , in my opinion team such as Hu tao. Not couse she is bad or it's not string enought but we already have 2 more than capable char doing enought work for vaprorize comps as solo hydros. And furina it's kinda too much work for too litle gains there.

In fact the ER% requirments i have calculated, and after talks with other TC those seems to match, are around the following:

1. Solo hydro sub 20s rotation 220%
2. Solo hydro 20s rotation 196%
3. Double hydro 20s rotation 151%
4. Double hydro 36s nuvilette roation 180% if not funneling her - 150% if funneling her with nuvilette E

With the help of Favonius in party , or even the F2P [With fishing] PIPE u can eachive and cut down those needs quite a bit. Making Er a NEED but not as bad as ppl portrait or are doomposting it. YET i would love to see an improvemnt in this. Maybe with a C1 change or more generation.

Damage and where to play her

Her damge it's NUTS, for a C0 char with a F2P weapon and very litle requimrntes and easy to build, she can compete and go over XQ or yelan in what she provide as damage and buff ro party, even if it seems that her hydro aplications are not as good and will not be the best for vaping always on every character alone. Compensating even for the damage you "would have lost" for running the healer for/with her, due to her buffs and raw numbers.

She has overalla very good and synergic kit that can be trowed around here and there, even if she can [Without a fontaine carry] only reach around 360 stacks with an healer in 18s. She seems in fact tought to work with and make work all, if not most, of fontaine character. And not be, even if very pleyable here and there, as general as the other archon [at least from this V0 infos].

For ppl calling her not usable or a Worst XQ or whatever else, i suggest them to see the full picture and not just 1 side of it. Maybe she will not improve your acocunt by a lot, but if u have a fontaine DPS it will arguably be better than anyother charcater till now [YES arguably even liney] .

She seems a pair mad in heaven for Nuvilette (Both C0 and C1) and it does not require any NA as Xq or yelan does for procking offield hydro, providing a very meaningful buff to all party, herself included. That could be very relevant in the future. Overall i HOPE in few fixes to her kit and maybe a slight buff to C2 damage giving it skill damage% and not Normal% if it's.

Let's hope for the best. I don't think she overpowered but it's nither worst than anyother hydro we have in the game rn. Even one as strong as childe XQ or yelan, that are in top meta teams since theyr realese.
