blair do you think that ships would "all stop" in space to fight? Or so you think battle lines would cross?
Then their is the honour harrington series where their is a battle line style stand off, and its hard to even see the enemy ships.
I need to go think about whether I would tell my fleet to fire thrusters and come to a full stop to engage or not.
BTW: Battles usually are a chaotic mess. Its the truth!

But seriously, it just does not look right.
In homeworld their was "fire while moving" and homeworld ships, you are right come to a full stop, but homeworld probably due to the Z axis, did not look like the commader said STOP all ships, prepare to fire. I think it may also look un-natural because without gravity you don't expect things to ever be at a full stop. Usually one side would be maneovering his whole fleet to escape or get a a better defense going, thus making all other ships move. Thats the nature of battle, I doubt if the sitting duck tactic would be used against an enemy fleet... he would just maneover to your flank too easily and outgun you. shielding himself with your own ships. Thus the need for 3D movement. etc etc
The jury is out for me on this one. Looks un-natural somehow not to be moving. If we had formations it may look a tad better. And I think when fleet menus come into it it may look better. Then we will have ships ,mixed together a bit more organised looking.
random chaotic thoughts really.
