There is a 2h demon hunter, she was in the quests in Azsuna at Illidari Stand from where I can remember.
But again, I dont care about weapons at this point. So you want Obliterate to perform better and hit very hard, Frost Strike to do damage and be a runic power dump (can just add in chillblains for mob slow with FF being on the target so the slow doesnt really need to be on frost strike). Could also switch the vulnerability to Obliterate to FF as well which just brings it back to the point of applying diseases first so you dont have to waste runes on obliterate against a target that isnt vulnerable to it.
Again I just wanted you to ignore the weapons entirely, both 2h and DW.
KM could also give an armor shred since we already have to get crit to proc it which would make that impact of Obliterate feel better since it would ignore some of the armor that reduces the damage output of the ability. Mastery could be completely changed to be that the vulnerability that FF would apply would increase the with more mastery, and apply to everything. It brings back the disease interaction that the Dk used to have, while also promoting good gameplay and brings Obliterate into mastery without turning it into frost damage making it just another Frost Strike that hits harder.
BoS might work better if it just replaced a dps cd. Could remove Frozen Pulse change how BoS does its damage and does a blast of frost damage to the target and a cone behind the target with the Breath of Sindragosa. Better than what we have with BoS right now while keeping some of its playstyle where you want to get the most attacks out during that duration, could also make it only work with Obliterate.
Now with that build. Just add the weapons in and create a 2h runeforge that combines Fallen Crusader and Razorice, use the weapon you want, you get your playstyle as well and so do other people because a lot of Frost players dont like this iteration of frost whether it performs or not. No difference in playstyle so balance is easy, everyone wins to the best as anyone could possibly get it.
And yes, Kirito had a DW skill, the only person to have it, which he kept a secret until Gleam Eyes. In other iterations he kept it a secret as well even if the system didnt support attacks with DW like against General Eugene and he didnt use DW in GGO but he used a sword in a way in the game no one seen before. I think DW is cool in the berserker side of things. Fury, physical damage berserker. Frost, initially a DW berserker with Icy Talons and hard hits amount to that of 2h damage, Kirito in SAO against Gleam Eyes and General Eugene, The old Studen Council President in Tenchi Muyo War on Geminar that got bloodlust in battle that just attacked anything that moved so her teammates should stand still and not get in her way.
The point of the exercise was to create a spec without weapon influence that both weapons could be applied to. That is what I have actually been advocating for.
Also, just through lore alone, Dk’s were raised from anything. Warriors, Paladins, if you fell in battle you could be raised as one of the Lich Kings knights. A knight is just someone who served his (or her) sovereign or lord as a mounted soldier in armor. They were the Lich Kings death knights, to serve him and to bring about death to bolster his ranks. His purpose was to create an undead army in the first place, its just Ner’zhul betrayed the Burning Legion yet again and creating this army for himself which I have heard was to fight the actually threat of the old gods since the undead are immune to their whispers. Eventually to possible fight the Void Lords?
The lore is all over the place and I really dont like using it.
