Acornicopia is too hard
I know there are a lot of posts complaining about how hard Epic is, but even the Master difficulty is too hard for what it's labeled as. Anyone who's Uncollected can probably 100% the Master difficulty EQ without any problem. The recommended team rating for those quests is something like 12,500, and you're probably rolling in with 30,000.
Master difficulty Acornicopia also has a recommended 12,500 rating, and the last three or four fights are always high level versions of some of the most challenging champs in the game, randomly selected so you can't even plan around them. The difficulty of those fights is basically Uncollected boss level, and you have to get past 9 out of 10 fights to make it worth the basket cost versus just slumming it in Heroic mode.
I know everyone's going to respond with "git gud" or whatever, but if you're good enough to 100% every other Master difficulty (or Heroic, or Uncollected, or whatever) event, you should be able to do this one too. Difficulty levels should be roughly the same regardless of the event, but this one does not seem correctly tuned.
