yea - puzzled me, too why the BHG would have 2 gunboats - i guess they got the old rogue gunboat, cause it simply fit into the line of correllian corvettes.
about the zoner gunboat - well, its not meant to be a fully comparable gunboat but a hybrid between a large armoured transport and a gunboat, i d find it strange if it would have 8 guns and could waste other gunboats the way the scorption or corsair toolbox can. - that always leaves the question why zoners appear to get the top military gear... and have no use for it at all.... cause even if pressed into defending themselves, they would mostly rather simply retreat than fight against the attacker.
about the bretonian gunboat...... well, its a vanilla ship... its cool and its - - - at least half a cruiser ( sizewise ) ... but the tommys were good as miniaturization when they made the battleship ( guess they employed a team of kusaris for it, while the bretonian team made the kusari battleship )
but - if you think that the zoner gunboat should have more turrets - feel free to add 2 more to it - or 4 more. - if you find space for them.... when i made it, i concepted it for 8 turrets. i don t really mind if its a "real" gunboat with 6 - 8 turrets .... or a hybrid gunboat.
