Highest Threat Tanking (13/7/51) (WOTLK spec)

Best Offtanking or 5 Man Heroic Spec

This build focuses on threat but is still great for any type of tanking.
I would personally use this in 5/10 mans or for offtanking in 25 man raids.
Proper Glyphs: Glyph of Devastate - Glyph of Blocking - Glyph of Sunder Armor
