Reliability as to what?
Is your main concern ripping aggro too easily? I am certain that a well maintained Sever Hate rotation would work. A Paladin of course would work. Several new items also greatly help dropping aggro - the new Discombobulate, the Positional Deaggro proc ranged item too.
If your concern is that you'll pull aggro too easily, I think there are a lot of items that will make your life a lot easier, and that is a good thing!
