The fallacy would be to believe anything posted here would represent "the masses".
It's very hard to design the game so that it fits each individual. And these threads are just individual opinions.
The OP is right - from his individual point of view.
My guild raids mythic as well and I was looking forward to it, but seeing how much work Legion has been since launch, I can't keep up with it - I have limited playtime due to work, family etc. So for me, the decision is easy - no mythic raids this expac, I'll just go with more casual schedule.
*shrug* it's individual call.
