Can VDH solo a Mythic Dungeon?

My friend keeps saying that a good tank should be able to solo any mythic+ dungeon and he sent me this video: The Ultimate WoW M+ Pug Tanking Guide
i tried to solo dawnbreaker 9 and could only survive for 5 minutes on the first pull as VDH, i have 617 ILVL, is what my friend says actually true? am i just that bad? i play with aldrachi

What does a video about trying to get over tanking anxiety, from almost a year ago, have to do with soloing higher key mythics now?

according to my friend good tanks should be able to solo mythics and not depend on the healer at all, he also says that if a tank dies it’s always his fault, he sent me this video to prove his point, but it’s from 10 months ago, i recently started playing, i don’t know if anything changed to tanks, but it’s been very hard to solo dg

Your friend doesn’t know what he’s talking about, ignore him and have fun.

Your friend must only have played with Blood DK’s or something. Prot War, Brew, Guardian, DH, pretty much always rely on a healer to pump into them while they stagger, absorb, or block the damage. Prot pal used to be able to do it, but they nerfed it a bunch so they could possibly solo a m0 but any keystones it most likely wouldn’t survive.
