Just wanna comment and say thanks for these man, you deserve way more subs. There's nobody else who teaches the main themes and focus of heroes in such a straightforward manner, everything else just focuses on builds. I find the discussion on what the hero is all about much more useful.
Like you said, the ember did really well but because they had a beastmaster the game is just over. Imagine if they didn't have a zoo offlaner and the game extended a bit as a result, PA gets her deso, maybe they throw a fight where ember gets silenced and PA jumps him. Beastmaster capitalizes on weakness, when your team is ahead he mulches towers and when you win a fight from behind he makes it more likely you get an objective off of that fight. Insanely powerful hero, I'm 11-4 with him this patch
