On the topic of the worry about bringing this noisycroak sound team to help with production, I'd like to note that on most of the Castlevania titles she worked on, Yamane-san was sharing the work with at least one other composer. The exceptions are Bloodlines, Symphony of the Night, Lament of Innocence, and Curse of Darkness. So most Igavanias saw her working with someone else. In fact, it seems like in the case of Order of Ecclesia, it was mostly Yasuhiro Ichihashi, with some tracks by Yamane.
Yasuhiro Ichihashi also worked on Harmony of Despair, and I would like to say that I also enjoyed its OST a lot (as well as the game itself). It may not be them specifically, since there was one other composer who worked on that, but I take this as a good sign.
