I played a DK pretty much since they were first available in the Wrath Beta. But to be perfectly frank, I think that while they have had their ups and downs, I think the fantasy of each Spec has been fundamentally misunderstood, and could be far better worked.
Here’s how I would redefine these three specs:
- Frost: The “Arthas” spec, Tank
I don’t care if “most of his skills were Unholy”, when you think about Arthas, you’re thinking about Frostmourne and the Frozen Throne. I would dive fully into that fantasy, with Frost wielding a single 2hander, a juggernaut that is meant more for taking punishment than necessarily doling it out.
Not only does it better fit the “fantasy” of a Frost Death Knight (a slow-moving, hulking behemoth of a man), but I think by tying its identity directly to Arthas (much as Havoc DH’s are to Illidan), it would inspire more players to take up the mantle of Tanking, which is always helpful in MMO’s.
- Unholy: The Necromancer, WC2-style Death Knight
In a more startling shift, I would change Unholy to be more of a traditional “Necromancer”. Not totally traditional, mind you; just more so. During Legion, the Unholy artifact, Apocalypse, did an absolutely incredible job of capturing the fantasy of being a melee-oriented Necromancer, where your attacks had you summoning a constant barrage of one-off undead for sometimes a single attack.
That was a really cool fantasy anyways, and this could bridge the gap a little more with the WC2-era Death Knight, who was also quite cool in his own right. If you had to put a specific name to it, I suppose Teron Gorefiend is about the only well-known WC2 Death Knight.
Also, by being a bit more “ranged” focused, it paves the way for a more unique interpretation of…
- Blood: The “new” Death Knight
While Frost and Undead serve as solid callbacks to Arthas and the WC2 era Death Knight, respectively, I would use the opportunity to reinvent Blood spec a bit.
It would be the more pure Melee DPS-spec. I would throw a spin on things by perhaps coupling their ability to drain blood (health) with abilities to also expend it. I would go entirely Dracula/Vlad the Impaler for inspiration for the spec, depicting Blood DK’s as mighty, bloodthirsty warriors, but also with a dark, supernatural/vampiric quality.
To give the spec a bit more defined “personality”, I’d say you’d want Blood spec represented by either some kind of bloodthirsty Orc (perhaps re-defining Nazgrim as a Blood DK?), or maybe a Blood Elf or one of the San’layn.
- In conclusion…
I think these specs would feel far more distinctive and iconic that the current ones we have. Sure, the current specs “work”, but honestly I don’t think any one spec is particularly exciting. They just don’t seem to convey a sense of identity anymore.
Speaking of which, now that we have so many dual-wielding classes in the game, I would legitimately propose removing dual-wielding entirely. I simply don’t think it fits the Death Knight class. As for the Legion artifact, just retcon it to a singular “Blade of the Fallen Prince”, and increase the size of the 1hander models to be suitable for 2handers.
