I think you need to add the list of bosses in Trial Of The Crusader..

Here is the order of the bosses in the new content.

Starting with first boss and down to last.

- The Beasts Of Northrend
- Lord Jaraxxus
- The Faction Champions
- Twins Val'Kyr
- Anub'Arak

These are the bosses that needs to be added, there is several guilds on atleast my server that has killed the open bosses in there.

Thanks.
