And this is important because...?
Do you really think, one second, that people who are impacted by those decisions will suddenly, out of nothing, stop, smell the roses, "enjoy" reading lore, and stuff?
The answer is "no". The people most impacted by those are not going to enjoy that, for one single second. They are going to grumble, and endure, because they have no way to affect their gameplay whatsoever. These people are going to be 60 at the exact same time. The only difference is that, given the optimal use of their time, is that they will switch to one of their dozen alts required for mythic raiding (because guess what? High-end mythic raider bring the class AND the player, not just the player), and level it instead. They are going to spend as much time poopsocking as they would. Just on a different character.
The only reason those artificial "week one/two/three" blocks exist is to provide a fake sense of fairness to the "MUTHICK FURST" crowd clamoring for their poopsocking, because woe if some guild might get "Mythic First" one week earlier because they poopsock harder than the next guy (of course, they will. One way or another).
This is yet another example of the metric-driven game design. They are at the point where they need to curate the game for the 0.01% who may "play too much vs the 0.02%"!
(and this is yet another data point that comforts me in my position that I am not coming back for this expansion, for the first time in the entire WoW history, and presumably not ever. I still enjoy the abstraction of World of Warcraft, but the actual product leaves me flatlined in terms of interest)
