So right now I'm lvl 47, and I have had a story for my Dragon knight since i started him. Simply put he trained at a temple since he was a child and was exiled when he got older for his thirst for becoming stronger at any cost. I am a Redguard using sword and shield and destruction staff with five pieces if heavy and two light armor. While I feel I understand the class pretty well, I am still having trouble deciding what skill deserve a spot on my skill bar.
Right now my bar look like this

I want to be able to kill anything pretty fast without worry. The other day i was doing Village of the lost public dungeon, and i must say it did not go well. I know i have to be a lot more careful being a vampire even though my spell resistance is over charged. Any ideas or suggestions?

Also I have not even set up a bar for destruction staff yet

Anyway thanks for reading and thank you in advance for any help you might have to offer
