I made an account to add my own 2 cents to this thread.

Personally, as someone who has played the game pretty casually for about a year, I absolutely loved the difficulty of the newer content. I thought it was perfectly balanced for level 90-100 difficulty. Sure, I died a couple of times but I had so much fun trying to figure out some of these mechs. I feel like like if it were easier I'd just be bored in the middle of fights. Endgame content should be more difficult than what we were doing 3 expansions ago leveling.

It's rude to tell someone flat out to "get good" but I'm also sure I didn't die once to the Honey B. fight on my first run. I was completely impressed with the new mechs and enjoyed the fight. It really is okay to fail a run a couple of times and learn how to dodge mechs and play through comfortably, not all players are gonna get things the first time, and that's okay... but I don't think its fair to call the mechanics too difficult in general when plenty of players will disagree.
