Blade's Edge Bomberman

The achievement requires you to successfully bomb 15 cannon ball stacks in 2:15 while not in a group. Unfortunately I do not believe it's actually possible and here's why. Starting the quest at the Skyguard outpost and mounted on an epic flyer the clock begins. It will take you 30 seconds just to reach the first cannon stack. That means it will also take you approximately 30 seconds to fly back. That leaves you approximately 1:15 seconds to bomb 15 cannon stacks.

Each time you bomb a stack there's a 5 second re-charge, which means you're wasting 14 x 5 or 70 seconds waiting to bomb something. There's no room for error. You must be ready and in position to bomb the next stack the second the re-charge is up. You'll have a total of 5 seconds to make errors. The problem and the reason I'm writing is to suggest that Blizz remove the bomb cool down or decrease the hit speed of the cannon balls being shot at you from the ground below. You see the cannons on the ground are all firing at you, 3 cannon balls at a time and they don't have to be all that accurate to hit and dismount you. If you're hit, which will dismount you or if anyone else is also bombing cannonball stacks there's no way to complete the achievement in time.
