Arena Filter is a World of Warcraft addon which adds class and role filtering options to the premade arena group finder.
For simple installation and updates, consider using Twitch for Desktop.
To install the addon manually, following these instructions.
After selecting Find a Group in Group Finder > Premade Groups > Arenas, you should see a Filters button to the right of the search field. Clicking this button will reveal a list of checkboxes for classes and roles to be included in the search results. Results shown only include those which contain a member matching at least one of the checked items.
Your filter preferences are saved between sessions, but are unique per character.
