The damage rate for your sonic tank doesn't unbalance things if it's weaker but faster but what about the image shape? If you need help with the image art then I'll be glad to help you make them. If you decide to change things further I'll also suggest you make your tank look like a light and stable combat tank with a rotating or non rotating turret that fires a continuous or non-continuous sound ray. I'm also making 1000 different Atreides, Ordos, Harkonnen, Mercenary, Smuggler and Sardaukar tank halls, turrets and vehicles that you can choose from which will be available to a few people though. I'll only make Atleast 12-80 good ones for each house for the public though.
