Pulling monsters with a Paladin is like pulling teeth. You have to be more sneaky than a Rogue when you're trying to pull a single aggro monster from a group of them that link. Sheesh, I have no idea how many times I've got swarmed and killed by Defias in Westfall when my Paladin got a million adds from nowhere...
I don't think those area effect engineering bombs will help very much, but if you do plan to go that route for pulling, go for the bombs and not dynamite. Bombs do less damage, add a bit of stun and have a smaller radius. The stun might be helpful if someone walks into the radius of the AOE, giving you a headstart as you head for the hills.
