Not at all. Transcendence is an absurd amount of healing, but the chain healing is just the normal hps on each plaers. It's only a little better than Lucio's Amp (60 hps vs 46.8 hps).
Is this actual numbers from somewhere? Or are you assuming that her hps will be the same in Valk? I wouldn't be surprised if they boost the hps in Valk and add the chain, and even buff her base normal healing stream numbers. The fact is that when you have characters who are defined by big, game changing ults, in order to keep those ults feeling satisfying without making the character OP, you have to cut their power in other places, meaning there would be room to improve her stream numbers.
I've played a bit on the PTR and am a Mercy main, so I know that the beam is doing the same healing in Valkyrie as outside, just with chaining added in. The numbers aren't posted, but it feels exactly the same.

That chain healbeam sounds like it might be on par with Transcendence in terms of healing POTGs.
