I agree that frost is decent enough in Raids. For PvP, I have no real expertise, but I will take your word for it that it is in a good spot.
But can you really say that Frost is in a good spot in M+?
To be entirely honest, I don’t care how the devs change our class. Yes, some people really want big Obliterates, and I suppose that’s why it’s such and important part of our kit right now, but for me it does not really matter which ability hits the hardest, only that our overall performance is adequate.
While I do dislike the Breath of Sindragosa builds, it’s more because it makes the Frost Death Knights really bad at handling any mechanic that requires them to step out of melee range for more than a few seconds. It we want to be team players and let’s say soak a meteor or something, we lose half our damage for the next minute and a half. It a really bad play style. The supposed advantage of BoS, is that if you can stick to the boss and maintain it for a really log duration, you will be rewarded with great damage.
The thing is… they made that really easy to maintain in raids this expansion. There are 3 factors that made breath builds really great. First, we have a lot of Runic power generation, just from our talents. Also, none of the bosses this raid have really bad mechanics that we have to move away from the boss to do. Also, they made all the raid damage magical, which give us loads of extra RP. Even bad players like myself can maintain 75%+ uptime on the bosses with breath.
Right now, frost is good in raids, mainly kept alive because of BoS. But what if the next raid has really bad encounters with lots of soaking mechanics, lots of movement, where we cannot capitalize on Breath builds to keep our damage high? Our damage will sink to the gutter.
If they have to scrap Obliteration completely and give us a new capstone, I will gladly welcome it, as long as it’s fun to play and give us more options outside of BoS. Heck, if they rework BoS a bit to increase it’s damage and give it a shorter cooldown, that would be also fine by me.
It does not really matter to me whether it’s Obliterate that does big damage, or Frost Strike, or Howling Blast, or Frostscythe. I believe that we just need to have a few decent builds that can shine depending on the type of fights or encounters you are in.
