I never said it would be a benefit. The discussion was about whether or not youcan tell live games and recs apart.Not a single thing you mentioned is a benefit of watching the games live, they're just a side effect. How is hearing the caster say "let me know when you are ready, then we can jump into the next game" any kind of benefit?
Edit: On a different note, I think players talking about the games in their streams is a huge benefit.
