My friends convinced me not to refund and we've been playing it a bit. The 3D plotting tool needs a kit of work. It's very difficult to accurately plot way points on it. Camera controls need to be a lot better. I think it'd help if they used the centre of the map as a zero reference point put x,y,z coordinates beside each way point as you're plotting.
I wouldn't worry too much about plotting indirect missile tracks in a multi-player fight. You'll be dead long before you get them off. Railguns and direct fire missile swarms combined with jammer seem to rule the attlespace when we play.
