I am rebuilding my characters up from level 86 and my key Skills have been Accuracy, Light/Heavy Weapon and Light/Heavy Armor. The rest of the skills don't really seem to be as necessary as you can use a high enchant item to boost yourself up. However, I am trying to find a 6th skill for my character. Since the Dual Wield Nerf from moving from Classic to the current version, I am experimenting with Block.
Also, is Block only intended to work on the front facing side?
