After you build her out, the HP thing is a complete non issue. Mine's still level 80 with level 0 artifacts and a level 50 Iron Sting, and she's already healing for almost 2k/tick. I've seen that she maxes out around 3500/tick if you really invest in her. The bigger issue is that outside of Superconduct teams, she doesn't really do much besides heal. I'd consider her BiS for superconduct physical teams (currently) though, with her role compression of doing electro pulses frequently and healing.After testing her I already knew she wasn't much of deal. Cool concept, but she has the same problem as Hu Tao(instant huge HP sacrifice on skill) . The only difference is that Hu Tao heals only herself with burst, while she heals herself or others with skill.
Dori is going to eat her lunch pretty much completely though, and probably won't have the HP loss at all. Another great character visual design ruined forever with a bad/outdated kit. She'll hang out with Amber, Sara, and Xinyan on the bench I guess.
Actually, both Amber and Sara could be saved if they just made a bow that does healing to the party like the Prototype Amber catalyst.
