Hello friends.
Just to give a little background about myself I've been playing World of Warcraft on and off for the last 12 years or so and primarily during that time the Death Knight class has been my main; I fell in love with them since the beginning and haven't looked back since. I'm more a filthy casual these days but previously I was in high caliber 25m heroic raiding guilds (before mythic days) and have done lots of PvP.
Over the last two expansions, Legion and now BFA, I have noticed Death Knights have gone further and further away from fulfilling their class fantasy though I will admit its mostly up to conjecture what that exactly means. However I will say Blizzard once stated they wanted DKs to be this dark, menacing and destructive class that while slow offer immense power and strength but quite frankly I'm just not seeing it. Yes we are slow and have few movement abilities but we're also not offering much in the damage or utility department either.
Watching the race to world first for 8.2 and not seeing a single Death Knight being represented made be sad. Granted world first guilds make up a fraction of player base and overall community, the fact remains we bring nothing to the table that is of value and we end up just being 'another class'.
In theory Death Knights should be one of the hardest hitting classes in the game but we're simply not. We don't offer raid utility like we use to with AMZ or haste buffs like Icy Veins and Death Grip doesn't work on half the mobs; meanwhile Retribution Paladins offer so much more while also doing the job of Death Knights much better.
FROST
I think it's safe to say at this point that most dislike Dual Wielding for Death Knights because it simply just doesn't fulfill the fantasy and the overwhelming requests to bring 2H back that continue to be ignored is saddening.
Frost has also continued to suffer from scaling issues and the always ends up needed constant band-aid touch ups as the expansion progresses as we've seen. It really needs to be re-designed from the ground up. Only one viable talent build for 2 expansion in a row is also pretty bland and testament to the specializations lack of depth.
UNHOLY
Unholy is a great spec and is also somewhat competitive. The one thing I will say about it is that DW if it's going to be somewhere on the class makes a lot more since on Unholy since it's all about spreading diseases as fast as possible.

Overall I would really appreciate if Blizzard could focus a little more on our class, a class that really hasn't been significantly looked at in a long time.
In my opinion we are just constantly overlooked: Same runeforges for 5 expansions in a row now, can't use any of the allied races, starting zone is completely out of date, offer nothing special or unique to raids or compositions and worst of all STILL CANT GET FROSTMOURNE!
