Try invading. It is great. It is so different from organized duels; it is like a brand new way of fighting. It will broaden your horizons, your way of thinking. You'll see there is a whole new world out there.
Here's a good way to start. Low level invading: http://tinyurl.com/8sql5ve
It is a good quality build that is versatile. You can use a variety of elemental weapons (you'll have to 2H str weapons, but they're usually best 2H anyway). Pick what weapons and armor you want and go to town.
I get constant invasions at this SL virtually anywhere. Doing this really helped my burn out, and gave me a completely different perspective. There is much more to PvP than dueling.
