What sort of wizardry is this?
A addon that does Cross server raid finders. You can seriously make or join a raid for anything with a name, description, and other criteria. You then wait for people to add them self to your wait list, and then you invite them or get invited. Instead of having access to one server, you have access to many. I use it for flex all the time and have used it to get shards, ordos, Celestial, and nalak when no one else is doing it (try getting nalak on a friday for your legendary cloak, it's impossible without this program).
