I was in the process of upgrading my level 11 Cannons to level 12 when I noticed the level 11 ones *look* stronger. Is it just me? The stripes on the 12 look mean but it's got a much smaller calibre! And guys, let's keep this thread G rated. There are kids playing this game - think about the children! (Level 12 on the left, level 11 on the right)
IMO, the level 11 looks stronger and it looks like it would fit a larger cannonball. The level 12 looks like a bee and the size of the cannonball would just sting.
The Level 13 ones kinda fix that. I think the caliber looks bigger, but even if it doesn't, those armored deflector plates just make it look ferocious.
