OK I understood you to mean that you went directly from Froyo to Lollipop.
I'm not sure what you mean here.
I meant that only because of it's looks (KitKat), I got bored of them(it) and I though Google probably ran out of ideas or that it would be really hard to make something new.. And boom, Lolipop material design pops up and gets my interest..
They did change some things that looks nicer, but dont really function any better than actions/look to which I was used to on Kitkat.
For example I could swipe down from the left half for notifications & right for toggles, while now I need to swipe twice times down for nothing.
Then there's multitasking where I could see multiple apps and just swipe left to close the app I wanted, while now I have to scroll through the app's windows vertically where one app windows overlays another just to find the app I want and swipe it away.
Now if anything different like this came to WP, people would start saying that It would confuse current users.. Oh really..
