If I only have time to do one daily quest, I do the one for the battlegrounds. If I only have time to do two daily quests, I do the battleground quest, Escape from Skettis, and Fires of Skettis. Yes, that's three quests, but the Skettis quests have been a source of quick and easy cash. I really consider them to be two steps to the same quest. Blizzard seems to be trying to make those quests less appealing in patch 2.4.
First they tell us that the Monstrous Kaliri that hinder us while doing our daily bombing quest, Fires over Skettis, have grown smarter. For now, the trick to getting away from those blasted birds is to fly straight up in the air until you're out of range. Apparently the next generation of Kaliri have gotten wise to that trick and have adapted to three dimensional combat.
Now Blizzard has informed us that the Skettis daily escort quest, Escape from Skettis, will have its reward turned down. I panicked a little bit at first, and I had to go check it out. It's really not that bad, at least on the Public Test Realm. The quest currently gives 9 gold, 10 silver, and your choice of either three Volatile Healing Potions or two Unstable Mana Potions. On the PTR the quest reward is 9 gold and 10 silver, with no fabulous potion prize.
These daily quests have been a reliable source of exceptionally easy money. The hardest aspects of the escort quest have been finding the Skyguard Prisoner and fighting over who gets to rescue him next. Once patch 2.4 goes live, the Skettis daily quests will be tougher and slightly less profitable.
