Black Orc is a bit more difficult to master due to the plan mechanic, but not by a lot, and the core principles of tanking are still the same. Guard, Challenge, Bellow. Looks awesome and can be loads of fun to play.
It is a good class if you plan on tanking. Objectively, even with some miskewed past changes, it is still the 2nd best tank on destro side, support-wise (mainly due to how basic SnB Blackguard is)
Make sure to get Plan B for easier ability management (specific for SM and BO). Can find it with most addons here: https://tools.idrinth.de/addons/
