I'd consider not learning Flash and looking at Toonboom Animate or Manga / Anime Studio.

There are also a few inexpensive Html5 animation tools such as Sencha Animator, A5 and there are a couple others you can search for. I tried Adobe Edge animate and I didn't like the folder structure it generated, but that's just me probably.

My view is the Creative Cloud subscription model is a mistake and I don't plan on buying into it.
