I thought about getting started in macro combo attacks for tanking, as earlier on, I mucked things up and spammed Tomahawk and Overpower (in Sunken Temple NM).

Anyway, here they are...

Threat - Heavy Swing > Skull Sunder > Butcher's Block
Healing - Heavy Swing > Maim > Storm's Path
DPS - Heavy Swing > Maim > Storm's Eye

...although, I may need to alter them for lower level dungeons.

Also, I thought I would need to use Provoke and Flash too.
