Which alternate upgrade for Inferno do you like the most?

a tempting mind immunity doesn't solve anything, because casting Confusion on an Inferno creature should be your last resort. and if you take new broodlings into the final battle, it's not surprising that you choose Imps instead of Devils to accompany them. I wouldn't be so categorical about Soulbinders. It's often more beneficial to make one long jump and then pull a ranged attacker closer, right into your heretical clutches, instead of exposing yourself to Zealots or Ogres. by the way, even if an Ogre ensnares you, there's still hope: many will be in plain sight.
