King of the Hill (KotH) is a damage meter that tracks highest hit per class, in addition to the overall highest hit. It has an attractive interface and visual feedback for events.

It also gives a good idea of how different classes rank in terms of damage at a glance. The max hit for each class is recorded as a class-colored bar, and the highest overall hit is at the top with the player name and amount. Reaching the top of the meter with the highest hit causes it to flare up in response. Mousing over the interface provides more information about the per-class hits.

It's very interesting to watch, and fun for bragging rights. You can also use it to record your highest hit while out soloing.

I hope you enjoy...
