Or for Juanito to piss me off enough for me to go kamikaze. I won a disproportionate amount of battles with only 5 cannons and conventional munitions only. I'm not sure I think the 1 coal = 1 shot with no other items as cost is quite balanced.
Compared to Old BM, 1 coal + nothing to fire the cannons really allows for intense amounts of warmongering with this strategy. It's not at all hard to Ramul for 60+ coal (I did it by auctioning off 2 DMND, 1 FOOD, 1 ALU and some other small things, roughly).
That, combined with 5 cannons spread shotgun across my land with a couple of land size upgrades gave me more than enough edge versus most of my neighbours. I only lost/drew with a couple, some of whom I managed to just re-outpost and re-engage afterwards anyway.
Coal miners might have this SUPER easy if they don't lose cannons over the course of a warmongering session. Just build 4-5 cannons across the grid, stockpile the coal and have at'r.
Yeah, I noticed that vassalages aren't particularly damaging to the vassal anymore. (NO MORE REPETITIVE TITHES, THANK CHRIST.) It's also tempered a bit by requiring an outpost before you can attack, meaning the cost of combat is 1 Glass + x.
