Seeing as no one actually is posting anything constructive,
If you look at the spec linked, it is a 61 deep void knight with 3 in paladin and 12 in warlord. You want to get to the ability to block with a 2 hander in warlord, but that is it. Point for point, you gain more reduction putting points into a different defensive tree. Void knight, unless this has changed, provides the most well rounded stats for tanking. the 3 points in paladan provide 1.5% block + 3% from shield block.
Its a pretty straight forward void knight, but using a 2 hander. While you may be tempted to max warlord thinking it is a tanking soul, it is just much stronger to grab 12 in warlord, and invest into a primary tanking soul. where VK gives 1% armor, 1.5% endurance, and 2% resistance, warlord only provides half of this bonus. I have not tried combining warlord with other specs, such as deep paladan, but im sure you could test it out. I use the 2H spec for tanking. Always have a sword and board just incase, but this spec will keep you alive well enough if you have passable tanking gear, IE. not trying to tank in greens in level 60 content.
