Yeah nothing stuck out to me except a few awkward moments on the first watch but after becoming familiar with the CR crew's vibe in the later episodes, it's incredibly cringey in retrospect.
They've never really said why he left and most Critical Role communities will shut down any discussion of it. Not sure why. It's a DnD game. We've all had to deal with bad players.
The cast refuses to speak about it out of respect for Orion, and most CR communities respect that and ban any discussion or speculation as to the reason for his departure.
Orion has come out since then admitting to having a drug problem, so that (in conjunction with the extensive list you posted) seems the most likely explanation for him getting the boot.
Also of note, he made his own spinoff audio series based around tiberius and his adventures, in defiance of tiberius being canonically dead in CR. He made a kickstarter to turn it into an animated series but evidently just ran with the money and the series never materialized.
I don't set an alarm because sometimes I do need that full rest cycle and I don't know how long it'll take me to fall asleep. So either 30 minutes or an hour and a half is usually how it goes. Occasionally the dreaded 5 to 10pm nap will rear it's ugly head, but only if I'm actually exhausted.
My neighbor kenneled his dog and swept the house, and I came over to feed his cats while he was gone. The floor was somehow covered in dog hair again by the end of the week.
The key difference is you can actually march to that music. Fortunate son is slightly too fast for a proper pace which is why the front of the one group was wavy and people were out of step. Also if anyone was actually calling cadence, the people on the left side probably wouldn't have been able to hear it over the music.
Didn't see much of it but the uniforms and equipment from every era was hella cool. They actually made it about army history, not a goose-stepping show of force.
