Just trying to give some commentary ... Its a lot of icons, and yes we get that they are horde. But some 'team' indicator of horde might be enough rather than present the horde icon over and over.

You might also not need to present the class icon in favor of the spec icon in the current play state. Its pretty common knowledge I think what a frost bolt means. In fact with a background you might use a muted class color for text

Something that might be useful would be dual spec icons where the icon is split
