Assault on the Ruins of Kra'nak

UPDATE:
There was recently an issue with the quest that has since been addressed. With that said, players who were working on this during the time of the fix will find that they are unable to complete quest progression. If you experience this, you are encouraged to drop the quest and reacquire before reattempting. Please note that you will lose any progress you have made towards this quest. This should only be necessary once. We apologize for any inconvenience!

Hey guys, we’ve discovered that the following bonus objective areas will NOT count towards The Time to Strike event quest due to a bug:
• Assault on Ironhold Harbor (Horde : Alliance)
• Assault on the Temple of Sha’naar (Horde : Alliance)
• Assault on the Ruins of Kra’nak (Horde : Alliance)
• Assault on the Fel Forge (Horde : Alliance)
• Assault on the Throne of Kil’jaeden (Horde : Alliance)

So until this is fixed, you should venture to other bonus objective areas in order to complete The Time to Strike. Sorry for any inconvenience!

If you don't have the quest then the area is not marked on your map. So, to get to the "bonus Area" fly to Aktar's Post (26.0, 38.9), then follow the path up east to about 24.2, 39.5 and you should get the "Bonus Objective" bar automatically.

Easy does it: there's a table at 17,43 (on the small island in the soutwest corner of the area) where a scroll respawns really fast. When you enter the island from the north it's halfway on the left side against the waterfront. I have tracked the respawn to less then 30 seconds every time (lowest was 13 seconds), so on average it will be about 20 seconds (3 per minute). Since each scroll gives 3% gain, that's 9% gain every minute, let's say 10 with the mobs that also spawn there. 10 mins max and you're done!

Especially worthwile when the area is flooded with players and thus very little mobs around.
