I honestly dont know what people like Haugs expect. Blizzard stated from hour one with the DH showcase that they wanted the class to be simple and efficient to play.
Im honestly glad that that is the way it its tbh, the days where I want to tryhard interesting and hard to play specs like MM in Cata are just way over considering how downhill each Expansion has went after MoP, and now putting so much hours and effort into the Game just to get steamrolled by corruption or oneshot PvE trinkets like on Beta is just not worth it anymore.
The biggest problem with Soul Rending is that they absolutely ruined our talent trees going from Legion into BfA. Fel Barrage for no reason got a horrible rework, making it only useful against 3 target cleave in Arena, Bloodlet and Chaos Blades got completly pruned and Momentum even combined with old VR talent is still not a spot that deserves a 110 row.
In Legion we only had to play Demonic + Soul Rending against classes that had sustained damage like spriests and affliction, apart from that we could have done some actual burst damage, even from range, which we clearly do not have right now apart from Eyebeam.
While UBC from Shadowlands gives us some on demand burst damage back, it once again will never work, I tested it for a few hours on dummies and it had the same problems when as an Azerite Trait, the terrain in WoW is just not made for this type of spells, causing you to either waste over half your fel rush if you want to land it or it just hits 20 yards behind you.
And thats the same problem again from BfA, they took away all our options and forced us into First Blood Demonic blade dance dodging everything. As usual, people QQ like they always do, having absolutely no clue of the class, and what did Blizzard do in return? They nerfed DH even further, crapped even moreso on Talents instead of giving options to not have to pick the obnoxious playstyle being the best one, instead just making it the tanky version as it was in Legion, but nope.
No one will play Momentum or Fel Barrage, no one will pick new Cycle of Hatred, Essence Break is still crap and both Desperate Instincts and Netherwalk will see even less play, if any, considering you have nothing left after Blur then. So enjoy a dumbed down version of BfA talents with no options for another 2 years.
You can have an reasonable amount of abilities right now in Shadowlands, but do you really want to play a more-annoying-to-play Colossus Smash version or a extremely weaker Fury of the Illidari spell, or a talent coupled to mobility once again that never hits?
Well done Blizzard, well done. How you can move from 3 viable last row talents to one is just +1.
