It's really easy to fall into the trap of being counter productive when criticizing a game development, just because you're never enough satisfied by improvements without realizing how complex it is to reach a final stage where everything is very well polished. And i have to apologize for this. I just want to state that in this new build i found a drastically improved pathfinding which, even if sometimes it fails, does the job pretty much well as i would expecting it to do in a final release. I guess it's for some part related to flocking behaviors which have been implemented. I also like the commander behaviour which is moving backward and turning (while firering) around itself while being attacked. It's pretty much realistic (i know this was allready in previous build). But all this combined together provide a very good feeling. I have just noticed that sometimes the commander stop building (maybe because it does not find the good path). I just give hime another direction and enter building orders once again and it works fine. Hopefully this will be fixed later. Is delta commander shoulder missiles planned for implementation or is it something which has been cancelled ? Congrats !
