Just a quick FYI, should you not get any loot from the world bosses.
Response from Blizz on my loot ticket
QuoteHeya!
Sorry to hear you had trouble with Levantus.
Don't worry about your loot, it'll be sent to your character automatically.
If it was gold, it will be added to your character right away. If you were lucky enough to win an item and it didn't make it to your bags, it'll be sent to your mail box by the Post Master instead :)
There is a bit of a bug with bonus rolls at the moment, they won't be offered if the boss is casting at the time it dies. Don't worry though, you can just kill him again. Make sure he's not casting when he's killed, you'll be able to use your bonus roll then!
Best of luck!
