Especially from someone who doesn’t play the class or raid anywhere close to that level.
I’m not disagreeing with you about the viability of Frost or DKs in general this season. Arguably the best tank for all content and two S-tier DPS.
People seems to not understand that Mythic race comps are strategically formed to kill the bosses pre-nerf as fast as possible + early season ilvl. After the bosses get their tuning for us regular players, comps are a bit less restrictive.
And DK is being used a lot during this pre nerf stage of mythic raiding. That’s the point. If DK was hated and not performing then DK wouldn’t be used. The later bosses are tuned very tight that you have to use the best.
Who trinkets a root? If you’re rooting ppl as a DK, you’re using the wrong talents. Also, it isn’t that easy to kite a DK.
