I think until House of Wolves, with Trials of Osiris and Prison of Elders, Destiny has done a poor job at introducing players to actual challenge. It has lead people into this false sense of "I am the best player ever" by making most of the end game content fairly easy or highly "cheesable". That is fine, but so many people I play with would rather cheese through a challenging encounter than challenge themselves to finish it. It's all become a going through the motions type of situation. "Just gotta get this done this week".
Confluxes are Hard in VoG. Most people look for a checkpoint beyond it. Bridge on Crota's End is Hard. Most people cheese this, despite it being one of the most fun encounters/puzzles in the game to me. Oracles are Hard. Most people cheese it by staying up top and sniping. Legitimate strategy, sure, but it takes most of the challenge out of the encounter, and because of this, people still get the loot and are lulled into this position that they have mastered the game because of it.
I think that's why you're seeing so many people complaining about difficulty with these new encounters - they've either never been challenged before by this game, or maybe they have, yet are much more comfortable getting carried, or cheesing to get the spoils.
Yes, they are hard as hell, the new bosses, getting to Mercury - all highly challenging activities, and all things this game has been sorely lacking due to the "easy mode" strategies that are able to be exploited so often. And while I agree that Burn modifiers on Skolas might be going a bit too far, the rest of the bosses have been pretty much spot on as far as challenge goes, in my opinion.
The changes to Qodron will help get more people through, and that could be good, but I don't think people should expect that type of rebalancing all the time. There are some parts of this game that you're supposed to fail on a lot. That are meant to challenge your play to it's very limits. To me, that's what I want more of in this game.
The only issue I have is with the checkpoint system on the Challenge modes of Prison of Elders. The time investment is too much to have to redo the entire thing from the get go when you inevitably have to go to bed after failing for so long. That and maybe lay of the Solar and Arc burns except on an even higher difficulty tier - maybe like a Monthly "Very Hard" Skolas rotation tier.
See, this just proves to me that you didn't really learn the fight or develop an effective strategy to beat it. If you did, you'd know that the adds actually do not swarm you at certain locations on the stage. The right side for example, the only place the adds can come at you are from the left side, as well as a max of 2-3 harpies from the front. You funnel everything through the left, and when it gets hectic, everyone ignore their tunnel vision on the boss and actually helps clear the 5 or 6 enemies that are starting to pile up on the left entrance. No Gjallarhorn required. Stop thinking that bosses should just be boss battles - and start thinking of them as boss encounters - adds are mechanics. It is very manageable, and within a few weeks I bet most people will figure out better strategies and better ways to get through it. Same thing went for Atheon, same thing went for Crota. The fact that 34 rotates into 32 the following week is even better, as it'll help with perfecting strategies on an easier mode if you find the 34 too difficult. Then when it rotates back around to 34 once you've mastered 32 version, you can try again with your new perspective.
