They may be unnecessary to you, but the new features will please the existing user base. The 'problems' you see are a lack of a particular functionality that hasn't been a major concern.
Yes, I'd like to see the DAM features ramped up a lot, but we'll probably have to wait a year before the next upgrade before you might see anything significant.
This is why C1 has become a mass market software.
Features for the masses, and lacking in core functionality like DAM and preview quality. And the masses eat it up. So the company saves on expensive coding to fix those confirmed issues. Expensive because this goes to the core of the software.
Instead Phase One tacks on some features which is cheap to code and leaves the core problems untouched.
It' all marketing - they can call this version with more features a new full version instead of an incremental upgrade - which it truly is.
A preview that is not exactly what you get in the output file makes a software useless for finer work as you cannot see what you are doing. And you cannot edit in 100% view.
Why would I want features if I can't correctly see what I am doing as the preview is bad?
If you do not see the difference between absolutely necessary core functionality and tacked-on features you are joining the majority of software users.
Which is why Phase One and many other software companies do it. It's a quick buck strategy, and they get away with it.
