The above hack is ruining World v World, over the last 5 to 6 weeks I have seen this hack become the norm from Far shiver Peaks, Riverside, Augury Rock & Abaddons Mouth. This is allowing players to fire Arrow carts over walls when the normal camera only allows you to target the wall.
Example: Defending Ogre watch Cut and we were attacked by a large group of Abaddons Mouth players, using the catapult stationed in the courtyard close to the supplies stash, I came under heavy Arrow cart fire (theses had been placed on the small outcrop in line with the gate at the fort.
Anet you need to fix this and ban the culprits as this is destroying the only thing I keep playing Guild Wars for.
Many Thanks Twig
