I just remember when Rikh streamed his progression on Twitch with Nihilum, it's basically the whole experience with Twitch chat being spastic too, "sacred vines"-memes and what not. Like it's not just you sitting there alone watching someone die over and over to a boss. It's a community thing and it's supposed to be a race where you can see what the "other guild" is also doing.

All valid points. I think that you underestimate the fun-value of watching someone fail repeatedly though. And no boss lives through 400 wipes these days, highest in mythic NH was little more than 200 wipes. And yea i went over the strat part which is obviously a problem, but i still feel that top guilds today are a bit too conservative when it comes to their strats. If you jump at the chance of copying someone elses strat that wasn't even made to cater to your specific raidgroup i think you might end up gimping yourself.
Gear is obviously also an issue that plays into the WF race, but thats just another variable to take into account. As you also say, you could use pre-determined templates that wouldnt make the raid trivial.
