What is Vendetta?
Vendetta keeps track of an Assassination rogue's cooldowns, energy and debuffs on a target and suggests what would be the next best move. As well as rotation suggestion, Vendetta also gives you icons to show when your Tricks of the Trade, Vanish and Cold Blood abilities are off cooldown.
Vendetta's options can be accessed using the "/vendetta" or "/ven" command.
If you do have a high latency and you would like a bit of delay between the next rotation suggestion and your input, I've created an option called "Energy Offset" which should help you out a bit.
I plan to add racials and Hyperspeed Accelerators to the suggested rotation part of Vendetta in future.
