Pyra regained its previous hull health and had its mass increased to just shy of the galleon, the use of the extra mass for ramming out balloons is becoming a plague of sorts.
Mobula had its side guns turned further outwards, breaking many/ most fun builds.
Muse have outlined a new approach to balance with the mobula being the first thing that will be looked at, the first balance patch from the new approach is still in the future though.
Squid gained acceleration and had its rear gun turned towards the side gun.
Minotaur got changed and overall buffed but lost arcs, rate of fire and turning speed making it almost as annoying for the user as the target, its still barely used.
Lochnagar changed, now deals 100% self damage over the gun's full clip size (after applying -60% clip size), its now better on the lumberjack, invalid on heavy flak and heavy carronade and exactly the same on the minelauncher. Hades, light mortar and gatling all gained some utility from lochnagar though the latter 2 being stupidly OP with it resuled in the original change being rapidly patched.
Heavy flak changed from 2 to 4 shots retaining roughly the same rate of damage. Greased, burst and lesmok rounds are now standard on it. (lesmok notably going from 1/2 shots to 3/4)
If you missed it the patch right after the pyra nerf introduced stamina and nerfed both the carronades, heavy clip and the flamer and was much more significant than any of the above.
