ViperWatch is a lightweight, mostly-text addon for hunters that performs a simple task: it nags you about Aspect of the Viper. With the changes in AotV from Echoes of Doom onward, some hunters will find themselves switching into and out of the aspect more often. VW simply allows you to set a low and high 'threshold'; when your mana dips below the 'low' threshold, you get a notification to turn AotV on, and when it hits the 'high' threshold, you get a notification to turn AotV off. The notification can be text, a sound effect, or both.
