The game really could use more cannon-type weapons, but I have doubts about us ever seeing "moderate to high" AoE damage for ALL jobs with Marksmanship.

Currently cannons are limited to the Culverin/+1, and the ammunition is limited to the Cannon Shell and the Heavy Shell. I'd like to see the cannon-class weapon expanded upon, even if not exactly in the manner Kingfury describes. The artwork for the weapons should also be expanded upon, giant high-delay cannons should be giant.
