I agree that a good design is a good experience solved. I feels like from your views that you are not permitted to take designs from conception to completion, and that may be the bigger problem here in our design world. We have become accustom to the idea that theres a UX person and UI person and a researcher etc. I have always pushed to be in meetings that are blue sky and I end my cycle in QA making sure things are pixel perfect, but we adapt to real time issues. I would challenge you to take on more UX responsibilities in your projects to keep design languages singular, there is no actual good reason we split up the duties at different companies.
