Lightroom cc (and photoshop cc) on iPad, healing brush is basically useless

First is the fact that it just doesn't work well at all compared to the  desktop versions. I'm not sure why but it's so far behind I find it basically on usable. Secondly, it's extraordinarily difficult to use with an Apple Pencil. There is no way to scribble over an area and I cannot even find how to draw a marquee around a given area whether it is cloning or healing basically using a finger works better than the Apple Pencil, which to me seems a serious miscalculation. 

I signed up for cloud to see if I could get away from a desktop workflow, unfortunately I find Adobe products so far behind on iPad, even compared to competitors like affinity,  I'm pulling my hair out.  The power of Lightroom cc is so far ahead of this version, but it also is terrible in tablet view in its own way...so even a windows tablet doesn't work. 

Is there any real explanation as to why the function is so bad, or why the Apple Pencil works so poorly?  Even trying to select a cloned area is basically impossible and just ends up making another one. 

Thanks for any thoughts. If necessary I can take a screen recording of the ridiculous Apple Pencil integration, if we can even call it that.
