The Quest Bomb them! is one of the most fun among the ten daily quests.  You can bomb the Burning Legion’s Fel Cannon ammo piles using your own flying mount..  You get an item in the shape of a smily round-bomb.  Drag the item icon into your spellbar so that you may begin the quest with as much visual range as possible keeping your bag invetory closed.  Click the icon on the spellbar to bomb.

Here is the fun part.  As you get near the Burning Legion’s Forge Camp: Wrath, you are greeted by many Legion Flak Cannons aiming and shooting fel cannonballs at you to take you down from the sky.  You should make evasive-action movements to dodge the fireballs.  The target of your own bombs are not the fel cannons themselves.  You gotta look for the Fel Ammo piles which are nicely distinguihed by redish-glowing Hunter marks.

It is recommended to fly low.  If you go too high and a fireball hits you, you get auto-dismounted from your wyvern/gryphon/nether drake and you fall to the ground.  Depending how high you are it could be a lethal fall or a minimal one.  Make sure to bring healing pots or bandages with you if you aren’t a healing class.  Once you fall, the fel fire sticks on you for at least 6-8 seconds causing 383 damage per second.  If more than a Fireball hits you, the debuff stacks.

Another thing to note is to not fly too close to the inner areas surrounded by cannons.  Stay in the outer perimeter.  There are two Wrath Corruptors (warlocks) who cast shadowbolts at you – causing 583-624 damage each.

Depending where you land when you get shot down by Legion Flak Cannons, there are other mobs you should either fight or run from.  Wrath Hounds (think Magmadar in Molten Core),  Wrath Speakers (six-armed demoness), Furnace Guards (Fel Guards).  Destroy 15 Legion Ammo piles and return to Sky Sergeant Vanderlip.  You can do this quest again in 24 hours.
