That's wild. Tanks don't have any mechanics in raids, raid tanking is literally the most boring dull thing you can do in this game. There is a reason no tanks ever want to do farm and they are the first people to lose motivation. Even on progress fights, you generally master the single tank mechanic (sometimes just a taunt swap) in the first 5 pulls and have to sit there for a hundred pulls more while the rest of the raid figures out how not to die.
