Blizzard please take into consideration, that you are allienating your playerbase with the design of Voidblade & Hungering Slash and Void Meta.
Demon hunter has the potential to be the “defacto” time friendly class. It looks like all 3 specs will use agility trinkets + warglaives. Then its the only class that has a ranged spec + melee spec that has the option to use the same weapons and therefore good if you dont wanna farm 20 m+.
But when the spec has movement in its rotation + a frost DK breath type Meta, you are now alienating the playerbase. You are taking the class that should be player friendly and adding Niches to it, that people dont want. NONE of the players i know likes Momentum, and actively will never play Havoc because it has it, just as many will never play Frost DK because it has breath upkeep that they dont like. It sounds like you are now adding both to the class that is supposed to be for the player that want the ease of not farming? That is the exact player that dont want this?
The base of havoc = Demons bite, Blade dance, chaos strike, Eye Beam is some of the best base kit in the game, as VDH Fracture, Immo aura, Spirit bomb, Soul cleave & Demon spikes is some of the best base kit in the game.
You have the foundation of 2 of the best ease of play degins in one class, yet you add movement in the rotation in form of Felblade (pls remove dog ability to play with expecially as VDH doesnt fit at all) + Vengeful retreat now being active part of ration + Fel rush active part of rotation (sometimes), This will all stop players from playing. Then you make Throw glaive part of rotation. This ability is known to just be a mob puller so when you make it part of rotation people dont like it + now you make a breath ability that is notorious in the community for being a main reason people will never touch frost DK, and has left it (me included btw)
To sum up: You have the posibility to make the by far most popular class in the game as it was back in the day, but you put in all of these hated things into the rotation… why? Just give us base VDH + Havoc kit as mentioned above, and make Devourer into a ret paladin type ranged class with a fun basic kit as well, and you have the most popular class in the game.
