Hmmm.... honest question what regarding tanking is hard ?
Because it is : Tankstance plus hit some Buttons.
Yes some or any, not even combo just damage,hit a couple of times this alone will hold aggro. Except somebody starts the "provoke is part of my rotation" game. Maybe turn the boss away from the party but if you need get told this with level 60 and above you never read or played tank in the MSQ or any other content.. maybe PVP but then that would be something else.
