Also leveling guide for someone who is brand new and have no gear etc [1.1.9.0] Beginner's Apex Death Knight
2nd place: [1.1.8.1] Drain Essence Death Knight -> CR 4:21 + 170ex naked 5:30/ SR 110/ Ravager 1:18 + Callagadra 1:27 + Mogdrogen + Crate (with the retal nerfs recent patch, it is still fine build of course, also require more rare gear than linked blade arc build - reason why I think this is 2nd best DK build)
