Blessed Blades doesn't really seem all that useful. Flow of Battle should give you enough cooldown reduction to keep up Horn of Valor and do your combo every fight. As the fourth skill I really like Payback Strike because it ends any debilitating effect on you and does decent damage.
I'm still not sure whether the Caliban or the Dwarven Crusher is better on the Templar. The Caliban combined with lifedrain rings gives massive heal on kill and the base damage is really high, but the Dwarven Crushers 75% dmg explosion can take out enemies outside of your combo radius.
Yeah, nothing's useful unless it lets you deal massive DPS when you have Caliban, eh? You don't say?
Well screw you. I've got four goddamn Longbows of the Griffon, a Blade of Red Birth or whatever the lv23 unique is called, a Song of the Marshes which is pretty much tied for 2nd best one handed weapon, a Superb Amulet of Dexterity, Strength, Ring of Armor Pen, and two enhanced crit rings.
AND THE LADIES LOVE ME FOR IT ._.
