I hesitated to share these as they contain cursing and are somewhat irreverent but I think the edginess is more around trying to be humorous and more importantly they cover Tanks and Healers from more of a Playstyle and fit perspective rather than just what has the higher outputs and are more "meta".

WoW Shadowlands: Which style of tank are you?

WoW Shadowlands: Your type of Healer?

Again please be forewarned that there is foul language and what not but there were/are insights in here that I have not seen presented this way elsewhere. For me at least while boxing I have trouble with mobility and typically would want effectiveness with simple rotations and fewer buttons and these videos try to answer from those perspectives (with humor to boot).
