Unless I'm badly misunderstanding what this means, it seems an incredibly poor way to decrease the overall wait in Elon. AR is (was!) already open for what felt an unpleasantly short time for those of us who (gasp!) still enjoy the lore aspect of the game. It already required a great many visits to even remotely have enough time to read all the lore stations around the inside, and now you've decreased that time further still? By an entire ten minutes?? Not good.
However, it is very much in line with a number of other breathtakingly poorly-made decisions regarding lore in these games (I say these because this applies most to the lore that carries over from GW1), such as placing the most engaging lore behind the RaidWall™. The decision to put all the most interesting additional bits of lore behind the most difficult gaming is the equivalent of giving out the university's most esoteric philosophy texts only to the football team. Or, if you prefer an ingame metaphor, like asking the Vigil to do the Priory's job and vice-versa. Seriously, not very well-thought-out. Not at all. Yes, yes, there are a few very visible exceptions up on youtube of truly excellent gamers with channels who do the raids, but these are the most exceptional of exceptions. Don't believe me? Try asking your raid group to just chill out for a bit and explore before moving on. Yeah.
Anyway, to return to today's point, it appears that once again, a decision is made that further reduces the ability to savor the immersion and depth of Tyria, once again sacrificing lore geeks on the altar of impatience and mass demand. Which, if you think about it, has a real life counterpart as well, which is why things like universities and such exist in the first place - so that those who wish to learn more have a place to do so. Sadly, no such parallel exists in-game, and it seems that even that which is available holds precious little worth in the eyes of those less interested in such things. This is all the more upsetting given how much more lore was pushed into the content under Mike O, which was just wonderful at first, but then more and more of it became harder and harder to access and explore, and now today we have decisions like this. Sure, it's all still "accessible"... but now will require an order of magnitude more visits to AR to actually acquire in full... the annoyance of which, if I'm not mistaken, is the entire driving force for this decision to begin with. Unfortunately, the problem was solved by reducing the small inconvenience of the masses (waiting for one or two cycles) by exponentially increasing that inconvenience for others (making them repeat said wait dozens of times).
The depth of immersive lore is the reason I fell in love with GW1 soon after launch, and the primary reason why, even after having taken several year+ long breaks for personal reasons, I've always returned to the game. And I know I'm not alone in this. It would be great to see decisions that, if they do not exactly accommodate those like myself, at the least do not actively further restrict our ability to enjoy this particular aspect of the GuildWars franchise, which once stood out so very prominently and made the game and the community what it is and has been all these years. It is a cornerstone of the franchise's success and excellence, and ought not be short-changed.
Just my $0.02...
