So after reading the responses I got to my original thread, I took into account a lot of things people wrote in response and calmed the f*** down. However, there seems to be some misunderstanding as to what constitutes accessibility, so...
1) Patch 2.2 adds the "medium difficulty" to end-game content that should have been there from day one for players who just want to see the story, but at the same time takes the higher difficulty of that content away from the players that wanted a grinding-their-teeth challenge and some kind of trophy for doing it to show off to their friends. So they are actually taking away accessibility to the content.
Think of other games with difficulty levels. You may not ever play on super-chillidog-my-innards-are-dying extreme mode, but you could still try it if you wanted to. That is what access is. This is a game where you payed for the higher difficulty on those bosses, but now they are going to remove the higher difficulty at the same time they activate medium difficulty on the same boss. That sort of flies in the face of what "accessible" is supposed to mean.
2) No special rewards/trophies for beating the harder difficulty level that isn't the same thing rewarded at the lower difficulty level. It doesn't even have to be stronger gear, it could just be a different coloration of the same gear, a specific achievement stating you beat it on hard mode (which is sort of implemented since you can at least see the date on the achievement, but that really isn't what I'm referring to), and/or some kind of unique pet/mount/furniture. The players who took on the harder challenge should be rewarded for that because that is part of the reward for doing harder challenges: The trophies and recognition that comes with it.
3) All of the content we see now will eventually get thrown into the dustbin of old content caused by ever increasing item levels. In the end, it wouldn't even matter if they preserved the old content because they are constantly pushing higher stats, which don't equate to higher difficulty. Instead, they just create higher bars of entry and completely trash the original challenge of the older content. Simply put, they are forced to throw out the old content with this model because they would have to keep rebalancing the old stuff against the higher stats to keep it valid. So again, the challenge associated with the older content that YOU PAYED FOR will be ruined by their model of progression.
