I want to preface this with I've never really commented on these threads before (yes I have cam here to read peoples complaints I don't really get angry at card games I've been playing them my whole life ) but in the last 48 hours I have gone from happy to extremely tilted, I liken this to Kibler getting annoyed by crystal core (before it was nerfed) but after getting tilted and thus having a bottle Pepsi spilt over me because of my being tilted I need to calm down and put my thoughts out into the ether.

I've been playing since the beta. I never hit legend just due to not having a lot of time in my days but with the quarantine, I had a lot more time on my hands I made the push to diamond 5 before the expansion and was soo happy that I could make the journey with plenty of time but seeing the way demon hunter has torn through the meta both before &  after the "nerfs" has not given me a lot of faith in their competence as a team. ( how did that class make it through testing in the first place?)  

• Skull of Gul'dan should be a 6 mana legendary - it's too easy for demon hunters to manipulate their hand with cheap cards to shift this card around. you are incentivised to play cards even if there isn't a need to e.g. playing a zephrys in the early game. just so you get the cost reduction.
• Altruis the outcast should not be able to hit face and maybe should be bumped up to 4 mana  - demon hunters have a lot of cheap cards that a lot of times can cause 3-6 in a single turn thus wiping your bord and dealing face damage as well putting you in an increasingly tight situation especially if you can't deal with it.  
• Battlefiend should be a 1/2  (i mean it's a better mana worm and mana worm got nerfed due to the fact that mage had cheap removal and ways to control the board in the early game)
• Twin Slice, in my opinion, is a big offender the fact that it's 0 mana and allows cards like Altruis to deal 2 damage to you and your board or because of how it allows you to manipulate your hand for Skull of Gul'dan or even the most ridiculous one of all being a 20+ damage combo with kael'thas. 
• Priestess of fury should not be 7 mana or it should be a legendary minion that can only minions, imprisoned antean was a 5 mana (now 6 mana) 10/6 that you had to wait for 2 turns for the delayed reward of damage randomly split but the card has a much better stat line and can just be played to deal 6 to the opponents face all they have done is move up the clock one turn and change the order instead of antaen turn 5, turn 6 wait  (or play a second one) then turn 7 antaen wakes then play priestess for 16 damage spread across all enemies, it's just antaen, then priestess for 6 damage then antaen wakes for an additional 10 and if by then you haven't dealt with the priestess it's even more backbreaking.  (I mean Ragnaros is a legendary minion that can attack)

I think this post from Reddit sums it up pretty well. demon hunter is a jack of all trades and a master of all I can understand these cards over multiple expansions but not all in one and thus people are more incentivised to play this class above all others.

note for something from me personally: 

hitting legend was the last big thing for me to do in this game but because of this meta where you basically have to tech against the most egregious aggressive class and if you don't face them you just outright lose to some others it's been tilting me more than usual and even when I take a break for a few hours I come back and nothing changed. I had thought about moving over to mtg arena as I've loved MTG since I was a kid and putting hearthstone on the back burner and just logging in periodically after I hit legend but after this, I might end up doing it sooner than I thought if the class isn't more balanced, for my sanity if for nothing else. anyway, I hope anyone who reads this has a great day. stay safe and (don't forget to wash your hands)
