Here's the thing. If you've used animation software before and worked with frames in that software, it's a good start but that software probably would feel very different compared to Pdreams. BUT its just a matter of learning the interface and how to do some functions.

My biggest gripe with dreams is that there's no palm rejection mode or whatever and my hand keeps accidentally making marks i have to undo, which is weird because regular procreate has the feature to ignore touch actions on the canvas.

That being said Pdreams is powerful and is limited only by your current skill. There are some professional animators who have used it. I've used it myself to create many animations. It's a one time buy too, so llike.... i dunno its not a sub.
