I’ll disagree on Helltides being bad.
I quite enjoy Helltides but they’re meant to be enjoyed in a small session, they’re not a “grind for hoirsnipon hours” type of an event. Hell, I’d even say the actual end-game (Nightmare Dungeons) should not be grinded at all.
D4’s end game is obviously catered more at those of us who are hoping to get 1-2 hour in a day compared to 3-4 hours per day (or more). I’ve been part of the latter crowd so I understand the desire and passion for that type of content but that is not what Blizzard appears tmight come in a season but I doubt it
