Let me give my observation as an actual Adobe CC Subscriber.
I pay $52 a month and get all their apps. Which is a reasonable price considering what you get and how many apps I use.
Their software is downloadable, but their CC Subscription is just a licensing engine that keeps track of users.
However, Adobe doesn't really upgrade their software with new features except about once a year.
Is it worth it? In the long run, it depends on your use of the software.
However, as a subscription service; it is only good if you are a person who always upgraded your software every year -- before the subscription model.
I personally DO NOT LIKE subscription based plans, especially if the software is browser based. The reasons are...
1) An online version will never have enough new features added to make paying all those fees worth while.
2) A browser based app can never have the same power as a Desktop app that has total access to the pc. I know because I do programming for PC software too.
3) Subscription based software is a bad ideal because it will alienate those who can't afford subscription based.
I am not against browser based software as long it doesn't limit speed and functionality.
And being a programmer myself, I know that having an application that is browser based is much easier to maintain and upgrade.
It is an ideal situation if it can work.
However, running a web application will always have limitations compared to software developed in C/C++ (or similar).
So, if you can offer a web-based app with a downloadable equivalent software... you will have more sales.
I am currently lining up alternative apps to Adobe's CC... and so far I have found all of them but a good replacement for Animate (Flash/Html5). I have one I am trying out; Opus Pro seemed like a good choice, but getting the software and support was very difficult... so I passed.
I then turned to GameMaker and Construct.... because they both have html5 export.
However, I was going to Buy Contruct 2, then i saw Contruct 3 with this ridiculous subscription.
Not only am I not going to buy Contruct 2 because it will eventually die. But, neither am I paying for software that runs on a browser that I have to pay every year, with little major feature releases.
ToonBoom's Harmony has the RIGHT Idea.... offer a subscription and a perpetual license to those who want to buy it out-right!!!
It's just too bad their pricing is ridiculously too high for a lot of beginners.
Be SMART Scirra!!!
Don't alienate beginners or those who can't afford or don't want to pay a subscription.
There are still a lot of people who would rather buy software out-right and run it for 3-4 years until a justifiable upgrade is offered.
It is actually cheaper for a person to buy it out-right than pay a high fee every year and end up paying for 2-3 versions worth with very little improvement.
It's too bad.
