I have always hated the fact that cannon are a single target tower. Cannons have always and will always do splash damage since a little bone and meat isn't going to stop a metal ball going 900 m/pH. Expecially when you have 100 archers bundled up in the same spot....
Here is a mythbusters video explaining what I am talking about
