The Fenris set is poifect as is. I have been using it for months now and love it. The speed bonus allows one to explore a land mass in minutes without worrying about stamina. It is also great for farming tar. The speed allows you to avoid being hit by the spew from growths, and the fire resist seems to really help if one does get hit by their tar. With the Fenris set I can clear a Fuling garrison without dying if I accidently pull the whole camp. It is also a great set for traversing the terrain and avoiding enemies in Mistlands, if one doesn't have the Feather Cape yet.
