I see a lot magicka DK builds that use one hand & shield and am wondering what the benefit/purpose is. I'm a VR4 dunmer DK and have destruction staff and restoration staff maxed out. I've mostly used two inferno staves but sometimes use resto on my back bar. I'd like to level a new weapon and am considering 1HS. Looking at the skill line the only thing that jumps out to me is the gap closer. Not having one in my skill lines that seems like a good thing to have. Are there other good reasons i don't understand or see yet?
