You dont need to have ilvl 700+ im running this on alot of dk`s at ilvl 650 (baleful) without any problems at all just use right talents/glyphs and your good to go . to be a bit faster use the 3 crafted items aswell (some of my bots have weapon trinket and chest crafted)
this is very true with dks, other classes especially rolling with dps classes need 705 minimum i find.
