Is she super expensive to build? Yes, is she good? Not really (only good at really high investment), do you need her? No.
Truck load of problems at v0 (can't buff, heal or cleanse the whole team). All of her problems will be solved at dupe 1 but she is not functional at v0.
Good enough buffer and healer at v1 but there are easier and better option to work around so why would anyone use her at v1.
If you are looking to build physical then you really have no choice but to get her v1. If you're looking at her v2 to use her in phase element teams then you can get her for that, but it's really inefficient.
Not recommended to low spenders and f2p as there better investments for way more return in other places (Springfield, Leva, Vector).
V1 is the breakpoint you want to make her functional, V2 will make her usable in every team comp but still kinda worse than f2p options like QJ and even something like a borrowed v6 Klukai.
She is a core supporter for an 'element' so if you want to use physical to it's maximum potential, then v6 is good but if you're looking at the bigger picture she will never be able to make physical better than the top 3 element (electric, hydro, burn).
If you want to use her in physical, she has only one good DPS option so it's not recommended, at least for now.
