Sorry, can't feel any sympathy here. All endgame content in every mmo ever eventually goes on farm. Once you've done it enough, you know how to do it, and the only way you're going to wipe and fail to complete it is if you have enough new players in the party/raid to overcome the experience and gear of the veterans.
Your raid point is disingenuous, you're implying that you'd be happier if AK was time locked as a weekly single run? Plenty of people are still using it to gear up with ilvl60 gear in all of their slots (which will easily propel you up to HM Titan, ignoring myth/phil entirely), running it a few times a week for a chance at those drops (and extra drops for other classes) is not a big deal.
SE hasn't cracked the magic code that makes dungeons fun to run week after week endlessly, surprise! That's not a new MMO issue.
If you're already at the point where you're farming AK to cap mythology and have HM primals on autopilot, perhaps its time to take a break from the game? You've beaten the story, you've seen every dungeon, what's left for you to do? Either go see the remaining content in the game via leveling other classes and exploring the world, help some friends, or bail out until they introduce new content! The game has been out for all of a few weeks, and many players here on GAF are still leveling their first 50.
I feel pretty much the same. If you've already put over 100h in a barely new MMO and you're already asking for more, well...
