I've joined Supremacy like a week ago and am enjoying it very much. I'm still in my tutorial match, so everything I say is from noob perspective, but I'm trying to improve .
From what I experience, ranged units such as artillery and Battleships perform poorer the further away they are to their target. At maximum distance I notice absurd amounts of complete misses, while at closer range, those units almost go berzerk. Like if they deal damage at e.g. 300% efficiency over short distances, but only 25% efficiency at maximum range.
Is this really the case or am I imagining something here?
