Currently only made for Druids!
Replaced the "rage: 100" stat on your character info panel with your current RPS (Rage Per Second)
As a Guardian Druid you want to have more then 6.66 (6.11 with 2xT13) RPS so that you can keep Savage Defense up an maxium amount of time.
The Rage is generated by auto attacks and mangles, and crits of auto attacks or mangles, but you still got to hit your target so hit
The factors that adjust your Rage Per Second are:
Haste - gives more auto attacks
Hit / Exp - makes your attack actually hit
Crit - you get 15 extra rage if you crit
This addon also replaces the tooltip of your Armor to display the damage reduction vs mobs up to 3 levels higher then yourself, just like the default ui does for hit and exp
