Nexus 6 random issues from stock topic

I really just want to document my experience with Nexus Support and Motorola.

I have been having non-stop issues with my Nexus 6.
Model: Nexus 6
Android version: 5.1
Baseband version: MDM9625_104446.01.02.95R
Kernel version: 3.10.40-geec2459
Build number: LMY47D
Model XT1103 / FCC ID: IHDT56QD1


Basically, I used the Google Developers page to install this firmware version.
Ever since then, I've been having the most bizarre issues.

1. The phone becomes unresponsive, slow to wake up, slow to type, slow to do ANYTHING


2. I enabled show screen touches on Dev menu


3. I can see that the screen knows I'm touching it, but it's not actually computing those changes.


4. After some time, it kinda wakes up and slowly processes my input.


5. It is only 'resolvable' by restarting the phone.


6. incoming call? Nah, you don't get to swipe to answer... call drops before it even responds


7. My LG G Watch will ring and my phone never will. I can't afford that.


8. Keyboard will provide haptic feedback that I'm trying to type, and the focus APPEARS to be on the search bar or in a hangouts window, but it never popualtes the text far.

So basically, I have had it.
I chatted with Nexus Support and spoke to Deven who told me that I should contact Motorola, where I purchased my phone. He also told me that the images found on https://developers.google.com/android/nexus/images are not valid for the Motorola purchased Nexus 6. I was very mad about hearing this, I only buy Nexus so I can get these latest updates. He said that the phone Google sales is the "Google Play edition" and the one that Motorola sells, he has no idea but it isn't the same. He told me to downgrade to 5.0 and wait for OTA upgrades to the "correct" version of 5.1. since I told him I installed 5.1 through that site. He told me not to tell Motorola about using the dev.google.com page to install 5.1.
Apathetic to Deven's support, I went to Motorola and chatted with them. Gave them the same story about my device. They escalated me to Level 2. I called Level 2 and the guy did an RMA for my phone because of the kinds of problems.
After the RMA was processed, I asked him if I should be using the Google Developers page to flash my ROM on my phone. He informed me that Motorola is aware of an issue and are addressing it with the factory images (basically confirming to me that using factory images can have problems at this time). I asked if those are being addressed in the 5.1.1 factory image and he confirmed. He said they're not sure on date but expecting 5.1.1 release in July.

I just wish I had a fully functional phone I didn't have to restart every few hours.

My Motorola RMA reference also mentions that the phone is (XT1112, XT1107). From another thread, I noticed that some people saw this from Motorola but also get another US version of their phone (XT1103).
