The simple truth is the Adobe has added bugs into Photoshop they are unwilling to fix. They do not fix bugs reported by users that have given us scripts like Image Processor Pro so these outstanding users leave here. Adobe has broken users work-flows removing features they used like Picture Package and Oil Painter. Lightroom is a heavy load to bear just to get jQuery and brrige output web gallerises can nor be customized well. You don't need light room to use jQuery.
Though with my subscription I can download and install Lightroom I don't. I tried some of the Lightroom betas which show me I did not want to used it so it was renoved. If Adobe wanted to change how one Process RAW files why did the not also change ACR why make users learn two user interfaced for raw processing. Lightroon is not a full fledged image editor you need an image processor like Photoshop with Layers support to be able to blend raw conversions to bring out some details. If your a business Lightroom Library may god send and something your IT staff can deal with. For me Lightroom is a maintance burden I don't need.
Using Adobe Products means high maintenance Adobe release code before they should bug force user to work around them and use older working version of Photoshop. Adobe support is not what it should be reported acknowledge bugs go unfixed release after release.
Photoshop is powerful but has a high cost I not talking money here IMO Photoshop price has always been reasonable for what what you can do with it. You need to put in a lot of work into Photoshop to get value out of it. Photoshop is not suitable for the general public.
