AffDots is a DoT Potency Tracking Addon. It's main goal is to ensure that you have the strongest DoT's possible on your targets and it does an extremely good job at informing you whether. It's main focus is on the Warlock community, but there have been ports of the code in to the Druid and Priest community as well.
Hermes is a raid or party cooldown monitor. It quickly allows you to watch for specific cooldowns from classes that you're interested in. This has many advantages to many people in the raid including, but not limited to: raid leaders, tanks, healers, and DPS. For more information you can contact me or check out the MMO Champion forum or the curse.com project page.
