Off the Top Rook

The randomness of Black Rook Rumble popping up really starts to annoy me. I've finished the other 3 open PvP quests between 20 and 30 times in the time it took me to get this one up to 6.

If you play one of the following classes, at level 110 you can learn the Tier 5 order advancement to complete a world quest every 18 hours:

- Death Knight: [order-advancement=432]
- Demon Hunter: [order-advancement=421]
- Mage: [order-advancement=388]
- Paladin: [order-advancement=399]
- Warlock: [order-advancement=367]
- Warrior: [order-advancement=410]

That includes PvP quests! It's a big time-saver and a welcome alternative for mount/achievement collectors who don't particularly like PvP.

For everyone complaining it is random, it is not. It is always up once a day.
To quote info posted by Xalan on the main PvP mount achievement page.

For those people who need to schedule their time to catch these 4 pvp wq when are up, they are on a repeating fixed 3-day rotation as follows:

Time: 0900-1500-2100-0300
Day 1:BRR-BBB-OMF-DBA
Day 2:BRR-OMF-BBB-DBA
Day 3:OMF-BRR-DBA-BBB

so you can predict what wq will be up and at what time on any day.

All 4 wq will occur in any one day. but they are not evenly balanced across all times of the day.
For example, BRR only ever occurs at 0900 or 1500 and DBA only ever occurs at 2100 or 0300.
