Not sure where else to post this, class guides seemed like an appropriate thread.

Anyways, I've seen a lot of guides, some say str some say arpen. I was just curious as to which is better at what gear lvl and all that. I know the rotation and everything but was curious about whether strength or armor pen is more beneficial to a dw frost dk. I guess I'm asking the same about gear as well, stay with strength plate items or go with plate/mail/leather armor penetration items. Thanks
