Let’s be honest here- most players stopped after they had Jaina-N or Jaina-H or whatever on farm, maybe they came back for the awful mini raid, maybe not.
Their goal? Come back day of the new raid, jump in, since that’s what’s interesting, and that’s what they’ve been able to do for years.
Blizz sees this, says ‘hey, we can get an extra 2 weeks of sub from all these raiders if we force them to do a bunch of dailies before they can get into their raid!’. And think of all the MAUs they’ll earn if people are out there, spending hours on dailies, it’ll just prove dailies are things people like to do if we force them to do it!
Brilliant!
Let’s not compare this to previous attunements, as flawed as they may have been, that required you to do relevant quests with relevant story to them.
This is them telling raiders you need to sub when the patch drops, not when the raid drops, from now on- because we want your money and we’re sick and tired of you nasty players just trying to do the content you like while avoiding the boring, repetitive content we want to force you to do.
