Actually an ele might be better suited to getting the title.
Achieving grandmaster is an isepid task of spider crawling on just about every wall you can find.
As I was doing it with my ranger, I started out doing running builds just about everywhere. But often found I had to switch to a fighting build to get most of it.
It is a mix of running and fighting that you will have to do. Running alone will not get it all done, imo. You will run into too many places where you have to get right up to an edge and spend a lot of time in crevices while trying to avoid mobs. It is much easier to just clear the mob and then move on and take your time to make sure you have fully explored.
I started out wanting to do this on my ele since he was my first character, but then switched to my ranger as he had more opened and could be more successful running. I wound up doubling back over previously explored areas a number of times having to fight just to finish it up to 100%.
I will not be attempting this on another character now that I have it done.
Just knowing where you are going and the types of mobs will determine if you should mainly fight or run. Just mix and match and you can get it done
