bigger higher class tanks should get a gun point modifier that increases as the size class of your tank increases
Example class 1 x 1
class 2 x 1.5
class 3 x 2 (and so on and so forth)
also when you add bubbles it should slightly increase your hp (with a max hp for every class but the last 1)
as in small bubble adds .2 hp
so adding bubbles isn't a useless measure.
