Idk if this is unpopular utau opinion as its concerning a specific community within utau.
English UTAU
English UTAU seems to be on the rise and we owe thanks to pioneers like Gumbi500, Sango312, and Cz (who gave us a standard reclist with CVVC). But over the course of 7 years, I've only seen progression in the amount of voice banks available for download and not in the much needed material such as ust's. From the CVVC days, ust's were scarce, currently, I still say ust for VCCV are scarce, or more so, non diverse. I can account for only three ust makers in the VCCV community that actively produces ust, and good ones at that. Everyone overuses the same ust because thats all thats on the market
This isn't anyone's fault as with a CV or VCV Japanese banks, making a Midi file, pasting in lyrics, and tuning are simpler due to having more familiarity and experience. English however takes more work (especially in tuning because of how the samples overlap.). However, when you have more people striving for making a voicebank rather than a medium for their voicebanks to be demonstrated, I feel like it defeats the purpose.
I've recently started making ust's of my own and once I'm confident in my abilities to tune, get the right pitch, and use proper samples for pronunciation, I will go back over them and release them.
some so far examples

TL:DR: You can't increase supply without having the demand available because inflation will occur. I feel this is the state the english utau community is in regarding the voicebank to ust ratio.
