Shattered Kingdoms

Enchanting MR is a good way to screw yourself over and preclude yourself from having any decent stat mods. It also will ruin your day if you ever have to go against physical ranged damage.

For some vets, having high MR is nice, but it's a huge headache to enchant for. The only real reason to ever enchant MR is if you don't have any better options or if you are playing someone who really doesn't want to get BoG'ed.
