I already know every encounter from a DPS / healing perspective

Tanking is very different from healing and DPSing, you need to know things like Possitioning and about tank swaps and one shot mechanics.

most guides you have to watch 15 mins of video to learn 3 things that I tank should do all spread out, can anyone recommend a place to view guides specificly directed at tanks?

Obviously I could just watch the regular videos like Mr Happy and MTQcapture or read basic guides for encounters but that would be 70% things directed at DPS / healers that I already know by heart and 30% what I actually needed, wasting a lot of my time.

Thank you anyone who can give a kind answer aside from "Read between lines regular guides"
