Classic Requirements for mythic bfa dungeons.

Hello! I'm a new player to wow in terms of late game content, I've ran some dungeons with a friend of mine and he told me that we could easily do mythic bfa dungeons, however they are not available for me. I have ilvl61, have not done bfa campaign and I don't have the heart of azeroth. Is the heart necessary for me to do the mythic dungeons? I'm not sure as I couldn't find any info on it. Cheers! via /r/wow https://ift.tt/35QxTLM
