Well I'm thinking we should be redesign out catapult to hurl greater loads, so more dwarves etc or a few minotaurs. By using a mix and match approach to our ammunition we could launch alternate waves for greater effect.
The way I propose to improve our catapult is to use an elephant or a mammoth, whichever is to hand as a counter balance. When the elephant jumps on one side of the cantilever, the otherside will be propelled upwards with far greater velocity. In order to avoid the elephant breaking the piece, I suggest we make it out of carbon fibre and titanium to give maximum strength at minimum weight (thus improving its mobility). Also I believe the cantilever should be teflon coated to minimise friction drag as the part moves through the air. Also I think we should add cupholders to the design as catapulting is thirsty work.
