It might be worth adding that the video is only looking at hiking through the countryside. In a crowded urban environment carrying a large sword presents a whole different set of problems.
This is patently nonsense. BY 5.24 rules, a player is perfectly free to play a plasmoid or a githyanki. That doesn't mean you find them in every major city. PC's are, by definition, exceptional. D&D is a game of heroes, not commoners.
But There are enough dragonborn in the FR for every major...
You are using prior knowledge of the setting and adventure though. Did you check that the DM hasn't relocated the adventure to Greyhawk, Eberron or a homebrew setting?

Cagney’s (?) home life was strained though, whereas Barnaby’s family (both) is always happy and supportive. That’s the joke (if you have read the original author, you will know that they are intended as a send-up/deconstruction).
We have been using both systems along side each other for years before the new edition came out. They work fine in parallel, which is better depends entirely on the situation. You have to convert back to spell slots for anything that's going to be around for more than one fight.
I really don't understand what this thing with entire companies of dragonborn mercenaries is. There aren't enough dragonborn on the planet for every major city to have a company of dragonborn. They might have a couple of dragonborn mercs in town, and maybe one or two in other occupations, but...
The Eberron chapter from Vecna: EoR is an interesting setting-based stand alone story that I was able to get some real emotional beats out of. It's appallingly badly organised though.
Sure, but you could easily trim out the less popular ones. Just do FR, Eberron, Ravenloft and Dark Sun. Exandria is handled by the Critical Role crew now, and additional material for the MtG settings is available through the card game.
