Warlock tanking

I seen videos with warlocks tanking dungeons and some raids in classic and this dude did even tanked 25 anub https://youtu.be/RS-mk2WMq8I

Have anyone tryed tanking as a lock? Not a lot of info online so i decided to ask here. Should i go full pvp gear for maximum stamina? I assume bosses have 5.6% crit chance- so its not mandatory to have a TOO much resilience.

This is the build i came up with https://rpgworld.altervista.org/335/...00000000000000
glyphs are Searing Pain, Metamorphosis, Soul Link.

If you have a guild and you all really bored - with few BiS healers anyone can tank some Normals, pretty fun times.

Other than that - it's just a meme.

Warlocks can solo most hc dungeons , and with a healer can in fact duo every dungeon. Affliction pvp spec or just affliction pve works aswell due to the increased healing you can heal about 10k a second if your geared correctly. A warlock can also tank most classic and tbc raids including soloing them depending on raid . A warlock can also tank OS10 and onyxia 10 and malygos 10 if there is a good healer with him. just look up Garloc soloing **** if you dont believe me or Skarfangz he also used to solo content.
