I hated tanking during leveling, but now that im 60 with almost full pre-bis for tanking I love it.
I usually: Cast regrowth/reju on myself. Cast the rage generation spell, charge, do 1-2 swipe then I start mauling enemies/occasionnal swipe. I usually have no problem holding aggro. People just gotta wait 2sec before going ham so that mobs can actually hit you so you can cast these 1-2 swipe at the start.
