It sounds like it fits one very specific scenario: a coder and designer(that had made all their work in AE) working together and the coder can now dodge the tedium of programming animations. However I prefer Hype (from Tumult) because it’s found that middle ground in simplicity while still being able to integrate real-world web. For that reason a designer(or coder really) can pick up Hype and not need anyone else. It reminds me a little of Flash, but the underpinning technology is javascript. For example in Hype it’s straight forward to build animated and compliant html5 google ads. That’s something a designer can do all on their own without any coding, the entire process is contained to that one app. Similarly a designer can make a fully animated reactive website and not need to touch code at all. Also Hype is $50 once. AE is either $240 per year or part of the Adobe creative cloud subscription which is around $600 per year.
