I agree, and I'll probably revert mine back to 4.4 as I said above, though I'll miss out on the better battery life. That's the clear advantage of a Nexus device: If Google does break something in a newer version, it's trivial to revert as they provide ROM images even after the device is out of support. The same can't be said for most of the other main vendors, who sometimes don't even make official ROM images available for restoring their devices.
