Yes. As long as you do it in time before the shields collapse, they re-fill your shield rings.
Thanks, not having done any combat that's worthy of talking about that side of ED is unknown to me. So the mechanic just sounds terrible. We don't want fights lasting forever but at the same time, we don't want to be vaporised in seconds. Get rid of this healing potion and weaken the weapons a little.
One thing I always thought a space battle needs is things to fly around. In deep space there is literally nothing, asteroid belts at least provide something but there should be other things, like huge hulks of dead and broken ships to fly through and use to hide or feint. Not sure how you could incorporate them but going in circles is pretty boring.
In any decent flight sim, you have energy, you have turn - you turn too much you bleed ur energy quickly. Different maneuvers are thus created to fight tactically. In ED, not sure if this exists, doesn't appear to be a way to get on someones tail. I remember a game I used to play with my mates by NovaLogic - Joint Operations. 150 ground warfare with choppers and boats. One time in a chopper I was flying at the time, little bird with my friends on the outside seats we get an aa missile launched at us. Ahead of me was a large chimney. As soon as I was passed it I banked, trying to put the chimney between us and it worked! I couldn't see behind but I heard it explode and my mates were all whooping as they saw it too. ED doesn't seem to offer any real flying in deep space but I suppose that's just the way it is.
