They’re not really different playstyles at their core though.
With Obliteration, you ignore RP outside of keeping buffs/debuffs up, spam Obliterate, use RW on CD, and throw in Rimes.
With current BoS, you ignore RP, spam Obliterate, use RW on CD, and throw in Rimes.
The whole “resource management” of DKs in general went way, way out the window with 10.0.
I played it back in Legion when it wasn’t great, through SL, and now because I enjoy the core of Frost - and I do mean the core. The massive devaluation of Frost Strike, HB/Rime, and Remorseless Winter with Dragonflight Obliteration has resulted in the absolute worst version of non-BoS Frost since S4 BFA. I enjoy the idea of Obliteration because I enjoy playing the core of Frost. When I think of Antorus FDK, that’s basically “the core” dialed to 11 since it was very fast paced and streamlined (for the time).
Current Obliteration is horrible and if Blizzard doesn’t want to reduce KM procs or pull damage out from KM, then the Obliteration talent needs to go and be replaced with something that actually facilitates using the core abilities.
Objectively, there’s no other spec that’s been dumbed down into a 1 button spam like Frost. Even simple specs, like Ret & BM for example, still have a more cohesive kit that encourages other buttons being consistently used and not just to keep up debuffs/buffs.
Subjectively, anyone that actually wants “big numbers with a 2h” can get a similar kick out of Ret or Arms, and anyone wanting their 1 button spam can find that in Survival, but they’re not 1:1 playstyles of course.
I guess we’re not playing the same spec friend because Oblit caps out in the high 400s/ mid 500s, and you’re getting those types of hits on Enhance/Sub/Feral without having to high roll every proc. And when you do roll procs for those, you’re pushing into 800s/900s/700s~ respectively
