No meddog. With the increased number of VH's, and the trees blocking the view to the others, it would be almost impossible to take a GV base with GV's alone (what is the point of them if we can't ?) when you add in the 17lbes and field gun respawn time.
For the artillery thing, we would have to get a range finder or something (say, down to 1k?), since the game would require them to be used as assult cannons withought knowing the ranges (artillery is an indirect fire weapon). I wouldn't mind getting a wesp and a priest (they actually COULD be used as assult guns, and have a chance of success).
