I’m used to Qtxfoxgurlyo posts being much longer than this, and it’s a bit awkward trying to figure out what I’m going to do with all this extra time on my hands after reading such a compact distillation of sentiment, but here’s a shot at engaging with the content…
Primarily I agree with your TL;DR, that really it’s pointless to even worry too much about output numbers when the beta is likely still very different from the final product that we’re going to end up with at official launch.
Regarding class “feel”, I do wish people would pay more attention to those aspects, and highlight them more in their critique of the current design. This can come down even just to something as small as sound effects or ability animations, and reminds me of someone in another thread talking about how they no longer play retail because the thunderclap ability has no actual thunder 
visual effect anymore. Small stuff like that actually adds up a lot to how it ‘feels’ to play a given class. I hope designers take it to heart that whether a rotation or playstyle is enjoyable comes down to much more than how large the numbers are.
