[PvK]

I have some ideas for cannon variations, but I think not for 2.5, because there are some Proportions 2.x games in progress, and largely changing a weapon that is likely in widespread use would tend to disturb the coherence of those games.

Which types of weapons would have more or less effects on shields, logically speaking, depends on what kind of shields you imagine. Some shields currently being researched actually only affect solid projectiles.
