@sylph_ said in T2 arty's are a bit broken:
@cortana In case this better-explains it - the blue shot in this picture is behind fired with less than half the power of the purple shot, (and less than half the angle!)
I know the heights are extreme. I'm using them to demonstrate that even when the range between 2 points is the same, elevation can make a massive difference to the maximum power or angle of the shots in order to allow a hit.
Supreme commander often results in shots blocked by terrain. This might well be the reason your artillery isn't hitting the enemies - assuming you were on lower ground)
I like this illustration, but I don't think it applies to my case. In my case, my artillery was at least a couple inches, maybe more, further back than the pink line here. The arty's weren't even attempting to fire up.
Going by your illustration, if you had artillery placed further back, I can see a trajectory for the projectile shooting up and over the edge of the hill here, and hitting their target.
