You wanted to make the game more balanced, but I can see that you've made the opposite ...
For me Rico and Fire are just cheated, you can put any other weapon against them with the same hull they will still win easy. These two guns are making too much damage (i'm talking for m3 or m4).
Then I saw you decide to improve damage on isida to not have long long time before the kill come ... but you just ruined the combo isida-hornet who was one of the best on this game ! Now when you have an isida-hornet against rico or fire, you just always die. Why ? Because you push down the self healing for 70% to 50%, so an isida can't self himself before he die, and you also push down the protection of hornet from 210 to 200 ...
So now, isida-hornet makes a little more damage, but can't self himself and don't have enough hp to be protected ... and against a rico or fire who are cheated, there's no way to win duel !
Then, make the game more balanced or make a refund !
