Wrath of the Teir'DalFollow

SOE did re-jig a few of the traits & abilities a few updates ago. Check by looking at your achievement window ('L' key). The first page lists all of the abilities available, highlighting the choices you have made so far. The Allakhazam Dark Elf Traditions guide does still list your Wrath ability, but I'm not sure how up to date it is.

If your ability has been changed/removed, you can remove the icon from your hotbar by dragging & dropping it outside of the hotbar.
