Yes I'm very familiar with them seeing as I own them and you're missing a bit of the point I was making. If Kanye wants to experiment with different sounds and develop as a artist that's completely fine, J. Cole is growing up right in front of my eyes with the transition he's made from The Come Up to Sideline Story to Born Sinner. In all of those albums he's had a distinctive sound while building upon it.
With Ye I see a artist who has continued to tinker with his sound while gradually moving away from got people hooked to him as artist. He's alienated some parts of his fanbase for it, 808's being the biggest example. I'm not saying "Hey Kanye, rap, flow and produce EXACTLY how you did when you first started", I'm saying stick to your roots while building on the new experiences you've had in your life.
But you are over looking an aspect of artistry in and of its self. You say "If Kanye wants to experiment with different sounds and develop as a artist that's completely fine"
but then to some extent want to place boundaries on how he does it. Just because an aspect of what an artist does caught your attention that does not mean that that is how they define themselves. What you refer to as his "Roots" may just been a page he was on at that time that is only significant because it is the spark that started the fire.
I have a ton of friends that are artist. I engineer and have spent hundreds and hundreds of ours in the studio when they are creating. I've seen people I know get buzzing off of stuff that they did on a whim or during a phase that they were in at a time and is no way reflective of what they are now or want to be doing in the future. This Idea of a "Core sound" is a box created by fans for what they like. 808's is a decent project if you listen to it outside of what you "expect" and album to be from Kanye. As an artist he should constantly tinker with his sound and why should he be a slave to some "distinctive" sonic elements that you a.ssociate with him if he doesn't hold the same affection for it? The Greats NEVER did that.
Some people are driven creatively further than others and as an artist he is doing what he is supposed to do, creating passion about his music whether its love or hate. If Ye was still in the vein of CD or LR in any way I don't think people would be as passionate about his music as they are. A friend told me you want them to either love you or hate you... nothing in between.
