Since I never saw any AddOns for the Hex CC, I decided to make one myself with insperation from the Sheep Watch AddOn.
Displays a progress bar for Shaman's Hex Spell.
And will announce to the raid/party/say chat, when the Hex is over.
Write /Hexwatch To get into the config menu.
Any questions or suggestions can be asked by adding my MSN -> Thomas_has_a_secret_msn@hotmail.com
