I was having a problem with warping too. Here is what I did to solve the problem... when I pull (I only use run3 so I don't out run agro) I cast either splurt or a low level (lvl 12 or under) spell to get the mob's attention. I run back to my pet. As soon as the mob reaches my pet, I tell him to attack and I FD. My pet now has the agro. At this point I can do pretty much anything I want - darkness, fear, slow, dot, whatever. Since I started this tactic I haven't been hit once by a warped mob.
Also, if you are get agro'd by your Shackle of Spirit you are casting it too soon. Let your pet take it's health down 10% to 15% before you cast it. I solo the undead all the time in Nadox, the Hole, Veksar, Velks, and the Umbral plains and I almost never have a problem.
