Well, after a lot of experimenting in pit fights, I think I found something that works. Here is my new strategy:

Standby: 8 Parry-Lunge 6
Opponent is Very Injured: 6 Lunge 6
I am Very Tired: 5 Tank 1
I Have More Health: 8 Parry-Slash 7
I Have Less Health: 7 Slash 5

As you can see, it is a lot more offensive. Most of my skills are offensive, and so I just decided to change my glad's focus. Thoughts? This seems to be doing a lot better than my last build. I still can't beat The Butcher, the last tier 1 arena challenge. At what level do people normally beat him?
