SHADOWLANDS! I will not update this WeakAura come Shadowlands since I am not using it any longer. It SHOULD however still work in Shadowlands but might be missing some new cooldowns that got added during the unpruning of the classes. If you need help fixing this WeakAura, feel free to browse around on the WeakAuras Discord!
As the name already states, this is a simple WeakAura that tracks all major defensive Cooldowns that are currently active on everyone in your group that has the role "Tank" asigned by World of Warcraft itself. They give you the icon of the active ability and the name of the recipient next to it. (see in the pictures above)
This Aura tracks both externals and personal defensive cooldowns by every tank and healer class in the game.
The WeakAura only works if you are assigned "Healer" as a role. If you want to change that you have to head into the "Load" Tab and disable the respective condition.
If I missed any big abilities, please let me know! Although please note - I chose to actively not track some cooldowns (such as the 2 brews from brewmaster monks), maybe I will add them in the future but I think, so far I have everything quite important.
