I started this addon to have only Health percent text and combat indicator...
But, for fun, i've made some stuff based on some situations and class, as described below:

- One different image for class on target
- Colored icons base on its spec on health
- Combat State Animation

- Percent health for player/target

Druid

- Different color if you are in mooglade, in respect of Elune..:-)
- Combat State Color

Everything was thought about the characteristics of the classes and their origins.
