It still comes down to execution. All the things you listed do not take much time for top guilds to figure out at all. In the end it usually comes down to every member executing near perfectly.
Personally to me, Alpha's stream is enough. I probably wouldn't watch Method or Exorsus stream and in a few tiers that won't even matter because at this rate the world first race is done in a few tiers anyway.
It says a lot that the most exciting part of this race for many have been watching Alpha. A two person race isn't exciting.
