That's the standard Unholy 2H DPS build, a good one.im using a two handed weapon on that build above and its sheer brilliance!
However i was using this build: http://www.wowhead.com/?talent=jfVMVZZfMhhhckgcsMcsut
What you think?
I have never had a char this high. Highest i have is a 57 warrior and another 62 DK.
Just dont really know whats best. I love my minion because hes like a tank for me and i can take on 10 65's at once and dont die.

I'd recommend the build I posted for leveling, it was smooth sailing and you can solo all the elite hunter quests in Nagrand with absolute ease.
You get a ghoul with the build I posted too, it comes in handy just annoying how it takes like 2-3 secs to come out the ground when you dismount.
