It is? Never noticed. It's fun, I have to admit. The problem many of you have is that you seemingly think you are the arbiter of what fun is and speak for everyone. You don't. Thankfully. You merely experience things within a narrow bandwidth and expect that everyone follows you. If I wanted one-dimensional fights with no real challenge at all, I'd play Classic. The game is almost 20 years old. Blizzard knows who plays and who stays. Some content just isn't aimed at noobs nor was it ever intended to be. Brats think they should see all the content because they pay for it. Let me reiterate that less than 2% of the subscriptions during Vanilla even saw a fully cleared Naxx. It was just sad Blizzard had to release an expansion and increase the level cap. I'm sure many would still be wiping in there and that's a good thing. Because what doesn't make you rage quit, makes you learn your class and get MUCH better at it. Or have an emo hissy fit, grab that TV remote and beg Blizzard for easy wins and watch the subs decline overnight. Why do you think Classic was so popular?
Challenging is memorable. Challenging is fun. If every boss wasn't faceroll and easily killed you wouldn't remember it in a year nor feel compelled to improve your Ui, your computer, your mods, your talents and your bindings and rotation.
What gets to me is how few of you even see this. If there were not people pushing for greater challenges most of you would have no one to cookie cut your spec and talents and even be manipulated by Blizzard bean counters to roll the flavour of the month class.... What a cowardly new world that has such people in it. Back in vanilla you had to work it all out on your own or find those that would show you where you went wrong. You either got better or were stuck in T1 or T2 content. -Most were stuck in T1 not because they sucked, but because they didn't' have good players to cookie cut from. ie Seasoned Everquest players who came to the very easy and watered down version that we call World of Warcraft. Everquest wasn't even that hard compared to Ultima Online or even Ragnarok online. Blizzard by no means created the first MMO and it was by no means the hardest of them by a long shot.
The problem is that Blizzard got greedy and felt they had to pander to the lazy cookie cutters and the target dummy dps types. It's a good thing but the problem is that they rarely see a wall and while being terrible Blizzard has convinced them they are good and can hang. There's really no drive to get good other than personal drive or the want to have better gear. If people were more well trained in their class, it would be better for everyone; less keks in PUG M+ and raids and PVP would be far more thrilling than the FoTM cookie cutter realm it is now.
Game is full of cookie cutters now who drone their way through content pretending they are good. They live in the shadows of the few who think things through, create routes and are always, ALWAYS pushing the cutting edge because for them it's all part of the challenge, which makes the game fun and playable even 17 years later.
Gone are the days of in order to SEE this raid you need to complete this group content in the world THEN join a guild, be social (it's an MMO ffs) and learn that in MMO gaming you will always be grouped with others to complete end game content. Otherwise it's not an MMO at all and you might as well go play a single player game. The sheer volume of keks I see on the daily in M+ is awful. Lack of interrupts, lack of mechanical knowledge, just cookie cutter target dummy types who then declare the content was hard but if they pulled their weight, it would be trivial. Get 5 well researched, strong players who understand the importance of mechanics and you are in the 20+ groups. Get 10 or 20 of those players and you are in Mythic raiding. Simple. Every resource is available them including walkthroughs of content yet they refuse to spend 5 minutes watching a video and will quite arrogantly expect me to waste an hour carrying them through a scuffed 15+ key which to me is like running Wailing Caverns. It really is that easy to do when you reach a certain level of skill in the game.
In the end it's Blizzards' fault for not teaching the keks how to play well. The class quests in vanilla ensured by the time you hit 60 you had a very good grasp of your class and the important stuff your class can do like interrupt and move out of floor candy. I can't stress how difficult the sub 10+ content is in pugging because people simply suck at the game. Half their fault because they have this drone-like approach to gaming, but also Blizzards' fault for not snapping the players out of their drone-like playstyle.
It's just a pity target dummies don't fight back and need to be interrupted. Then again, they'd just never touch a target dummy so ... ugh.
