I hate to be THAT guy and again, i've been advocating for and defending Construct against criticism in the past but as someone who animates for a living this is just very close to heart...
As a background, I produce animation for corporate training and educational purposes, lead a team of two people as a creative director for a fortune 500 company where we produce a lot of animation and freelance for more "fun" projects next to all that like i.e. a credited brief stint as an animator on an adult swim show.
I've worked with After Effects, Flash (now Animate), Moho Pro and, my favorite, Toon Boom Harmony Premium.
There is absolutely NO WAY that i would use Construct for animation over any of the above mentioned software packages, which have literally decades of development behind them and were very carefully catered for animators and suits all their needs.
When it comes to producing HTML5 animation for the web, i'd either go with Animate CC, which i rarely use these days but it comes with our company wide CC subscription OR, would look into Rive.App, which was recommended to me by my colleagues and seems to be a really robust piece of software that is very similar to tools found in the above mentioned packages.
I maybe used the Construct timeline once or twice in my projects since i found it to be extremely confusing and non-intuitive. If i have to think longer than 30 seconds about how a timeline works, there's really something wrong, sorry, but by now after using so many timelines, this is just something so standardized, that it should work in a more standardized way. Beside that, in my experience the timeline used to crash a lot. I don't know how it is these days, it might be better.
In any case, the claim that Construct is the "BEST and EASIEST" animation tool to me is just either delusional or simply a very bold claim that can be debunked and backfire very easily.
Construct's animation features are just very clearly developed with neither a clear understanding of animation workflows nor any sort of input from professional animators and it shows. The interactivity might be nice but it's probably already a total overkill for most animators, who definitely won't spend the time learning the ins and outs of the event sheets. As intuitive as they are, they still need time to learn. Compared to something like Rive or all your usual prototyping tools like Figma or Invision, which can export HTML 5 and offer easy(er) to use interactivity features as well, it's really not all that intuitive as you might think.
Again, i don't mean to be nasty or criticising just for the sake of it but it seems to me, that Scirra tries to enter a market that they neither really understand the customer base nor the competition. They saw an opportunity to kill two flies with one blow with the timeline and went for it, which is commendable, but for Construct Animate to be in any way a consideration for animators it would need a HUGE and i mean HUGE, probably months to years, amount of research, programming, testing and marketing.
I just hope they didn't bite off more than they can chew and hope they really go in and look at whats out there and what the people they want to sell this to actually need. Which also brings me to this: WHO is this for exactly? WHAT animators? Motion Graphics people who work for video? Definitely won't use it, and one video export option with a file format that is highly compressed won't change that either (usually you animate either directly in the compositing software or export image sequences and then go to compositing or some ProRes or other video format with less noticable compression).
Character animators, game animators, UI designers, etc. etc. there is really no clear indication, who they want to develop this for...
I've never been this critical of any of Scirra's decision and i've been with them since the early C2 days and was a day one adopter of C3. But this project, to me, doesn't seem to be under a good star, unless they are willing to put enormous resources into it and i can't see how that will NOT affect C3.
But just my 2 cents, rant over :D
