Depending on what 'set' of dailies are up for the Klaxxi, there is a special hidden bonus daily. They give the same amount of rep as the other dailies but having that one extra turn-in can add up over time.
The Briny Muck / Zan'vess. If you happen to be questing in the area, swing by and kill Kypa'rak. He will drop Massive Kyparite Core, which starts Kypa'rak's Core.
The Clutches of Shek'zeer. When questing in this area, you will be able to spot Karanosh. Same idea here - kill her, loot Enormous Kunchong Mandibles, start The Matriarch's Maw.
Terrace of Gurthan / Forgotten Mire. Finally, if you get this quest hub, go kill Warlord Gurthan for his Ashes of Warlord Gurthan, which start The Warlord's Ashes.
