The mixer just works. You can use any of the many 3rd PTY chainers.
The mixer currently has great ergenomics, is tactile and 100% backwards compatible
The mixers in PT, Ableton and S1 are a mess and so much backward.
Cubase is NOT a clone of any of the above neither does it has to tranform into one.
Steinberg needs to stay true to it’s userbase and vision of a tactile interface.
That’s why people chose Cubase.
If you prefer the competition, just shop with them, pretty sure you’ll be back soon enough 
Learn how to use FX channels as well, instant 8 additional inserts, parallel processing etc.
Be REALLY creative. Don’t claim to be creative, while not using everyting at your disposal already. That’s not creative, that’s shortsighted.
If steinberg would ruin the mixer legacy with endless scrollbars, performance issues and sound design matrix modulation issues, they would stab their userbase in the back.
KISS principle
The mixer IS NOT a “sounddesigners dream” you’ve got plenty of shitty containers and chainers, to go crazy on “sound design”
The mixer should be an efficient / ergonomic signal router, nothing more, nothing less.
