I just wrote this wall of text and then deleted it. I redesigned everything that "is" a hell tide to make them more interesting and cool. From top to bottom, with Demon NPC factions that invade each other, with each faction dropping specific cosmetics and equipment. To win and fail conditions of a Hell Diver's 2 type of campaign with the Hell Tides, etc. But its whatever, and just feels more annoying that I can come up with better shit in a handful of minutes than the fucking DESIGNER's of the game can.
The Rogue-Like features in the new Infernal Dungeons seem boring and lack luster. They should remove any mention of the currency from the powers and just add stronger Ying and Yang properties to each one. The currency reward being based on your kill rate, or some other easily trackable way. Throw some boss mobs in there while the other demons are still spawning etc. The "Council" or whatever will be novel the first half dozen times, but this sounds like something you'll run 100+ times.
World of Warcraft's Delves are being added. I guess they felt like the game needed a dungeon thats in between the length of a Cellar and a Dungeon (which is kind of true) - just hope its more to them than what the Cellar's generally reward.
They're adding "sounds" to certain uniques and legendaries, which I'll give them props for doing. The Spriest Legendary weapon from Legion was always talking shit and making the odd sound and I really enjoyed something that.. for what its worth is a relatively brain dead feature. I also like that they're adding a couple more trash NPC's to the mix as Diablo 4, although its not New World levels of repetition, its still pretty bad. I think their idea is to make the bosses stand out that much more, but hell.. whenever I actually buy the expansion, I'll appreciate the new "diversity" hires I can kill.
