HOW OFFENSIVE, WE SHALL BE PLAGUING OUR ENEMIES WITH DISEASE, LETTING THEM FESTER AND GROW TO BECOME CANCEROUS PUS-FILLED CYSTS THE SIZE OF FOOTBALLS AND MAKING THEM EXPLODE AND GUSH ONTO THEIR NEIGHBORS AND INTO THEIR BLOODSTREAMS
WE ARE THE BUBONIC PLAGUE
Can you tell I'm excited?
OT: The blood changes are pretty significant, and it's actually something I look forward to playing as an off-spec for sure. Frost received the changes it needed for a long time since they've shed the dead weight of 2H (Although it would have been the same if 2H stayed and they lost DW, it was balancing issue). It didn't need too much to be honest but obviously this is a subjective matter. I have quite liked playing DW frost for a change away from Unholy, I won't lie.
Unholy however, from personal experience of the realms I've been on and the DK's I've spoken to in-game, isn't too popular nor interesting, and I don't blame them for thinking that. It's a dot-class with a pet from the outside world, not to mention there's more preparation that goes into dpsing compared to frost.
I love Unholy and the way it plays, but a change is a breath of fresh air to say the least. Lore wise, circulating around diseases that, in their words, "burst", is pretty cool and gross. Really appeals to the morbidly curious person that I am.
