When I get back to updating the guide (may happen this weekend, not sure yet), the next section is on firearms and cannons by extension. I talked about it with Prime32 a couple pages back how to manage cannons and came to the conclusion that the intersection of firearms and cannons and siege engines in general is an unclear mess on how it's supposed to be managed, like how you're supposed to load or aim the thing and whether firearm or siege weapon rules play precedence in that. Also how long it takes to Aim and Reload, considering those tend to be in rounds.
In any case, you'll probably look something like Ovan from .hack//Roots: (warning: big picture)Spoiler
