Make max rate increase the more you fight vs other people, reseting as soon as you enter a safe zone or press the ez verb (a check would be made for pc id/ip so people dont use their own alts to boost the rate). Some ways to promote even more pvp would be make village raids have some kind of big reward(lets say kill 3 enemies and leave the village alive would give x ammount of exp and money), add the village scroll so many people asked, add pvp obtained tittles (reach certain requirements for a tittle), etc
