Only if your guild is douchey/stupid OR you're legitimately playing worse than everyone else. Like, DKs aren't in a good place but it's not like they can't compete. Balance is really fucked at the high end, SPs and Ass rogues and shit, but all the plebs that play the normal specs are pretty balanced even if you're on the lower half of that.
Heroic logs meaning literally nothing important. If you're saying not to use Mythic because there's literallynot a single 'single target' fight on mythic....HEY YOU'RE RIGHT. The small amount of cleave you gain on those fights on Mythic is inconsequential to the results here though, and more importantly is useful damage. The number of purely single target fights in raids is meaningless, so even if you want to assume parity between RA and FSC, FSC pulls way ahead due to encounter design. Since that's not the case, the best you can do are the mythic versions of those fights, since heroic is not remotely relevant for looking at parses. Even looking at heroic, the top parses are all within a few thousand of each other and MOSt of those are still froscscythe. I guarantee if you put me in a group trying to do heroic (IE a sub 3 minute kill), I would beat every single parse on that board. So you buff the RA spec. Great. Now that's 10% stronger, except you've lost ALL cleave in the process, which still makes it the wrong choice on the majority of fights. Throw in the pillar of frost bracers, which are stronger for FsC than the ob belt is for obliterate, the razorice buff helping Fsc significantly more than Obliterate, and I bet Ob is the better ST choice, but it's barely going to be ahead. These buffs are probably enough to bring Frost ahead of Unholy on single target, and are reasonable given that DKs aren't like TERRIBLE for the reasons I outlined above (low/mid end class balance isn't bad), so it's a welcome buff, but it's not huge and it has VERY real drawbacks (loss of all cleave)
