You spent a lot of time in TWM saying that people should be made to understand the lore behind bosses/raids before they can enter said raid. I don't understand why you think that making players do something they may not want to do is a good thing? It also seemed that the sole value attuments had to you was as a extra vehicle for the game's lore. Attuments are an extra barrier to content. Now, I, personally, wouldn't mind doing some quests that tell me more about the lore behind a certain instance or boss. But I'm sure there are many, many players who would.
You posit that you should only be able to enter a raid instance if you have been (force) fed a set amount of information about that particular instance. But, does making players undertake a series of quests in any way ensure that they will know more about the the raid they're attuning themselves to? Those players who don't want to learn about the lore are just going to scroll down to the bottom of the quest page to where it says "Kill such-and-such-an-NPC" and move on. Just because you're making them do a quest doesn't meant they're going to soak up the lore you're throwing at them.
Why not simply have a series of optional quests outside each raid instance which allow those players who want to learn more about the lore to do so. I don't see the point of tying those quests into your eligibility to enter a raid instance.
