I've been defending the DK gameplay since the release day of Legion.
You told us, that Blood is useless. And you also told us, that Frost and UH is not competetive.
I told you that's BS - all of it. And time showed us, that you were wrong with everything you have been thinking about DKs.
I can tell, that the BFA version is even better across every spec. So before you embarrass yourself(save other casuals from getting confussed and distracted), maybe swap to alt or quit the game.
You actually just frustrating people and taking away thier joy - people, who just want to see opportunities, rather than limitations you will try to point out.
Thanks.
