currently the nanodrone will restore your hull 100% automatically, in reality that wouldn't happen, it would take time for them to restore it and it probably wouldn't even be to 100%. So, why not make a change to them where they recharge your hull by a % every so often. let's say around 500 hull every 2 minutes with the possibility to have them stack up to maybe 2 or 3 of them going at once.

if that is done I can see two ways for it to work. one is for both or all three to be repairing the ship at once giving back 1500 hull every 2 minutes or so, OR, have them repair every two minutes from when you activated them.
and I was thinking of having each one last for an hour or two.

if you activate one and then activate another a minute later you'd get 500 hull back every minute.

it would change how people go about pvp.

counting the number of times repair nano drone has saved my ship from certain disables... I say -1.. Repair nanodrones is way better than the repair button, its cheaper than 200k repair without the 5 minute delay.

You only got 200000 repair bill? i'd use that repair button all day long!
