Last post, I promise. As everybody said it even before the nerf went live, Death knights are not a viable class as of right now in PvP. Thank you for ruining both battlegrounds / World PvP and even the chance to have a little bit of fun in Arena. You forgot to nerf our dmg tho! Here’s a bit suggestion 
Frost
- Obliteration damage reduced by 50%
- Frost strike damage reduced by 25%
- Remorseless Winter removed ( It can bring out stealth classes, so we felt this makes Death knight extremely overpowered)
- Runeforging reworked : DKs can no longer use runeforging after reaching level 55
Unholy
- Dark transformation no longer buffs your ghoul, but the cosmetic change will stay
- Festering strike now deals 100% increased damage to totems but nerfed against players by 35%
- Wound rework : Wounds no longer pop if you hit them with Scourge strike
- Abomination no longer has cooldown, but it’s damage is decreased by 98% and while it’s active your death strike heals 350% less.
Don’t be angry at me if you see some of this in the next tuning patch
