Don’t agree - cautious also pulls a ship out of the line of fire. I’d suggest adding a behaviour to cautious where if it can no longer repair and it hasn’t been shot at, it returns to battle as normal.
Maybe repair modules could regenerate their resources if they haven’t been used in a minute, say? -Edit- Actually, scratch that. I’ll just try and make a fleet that rotates armour-monsters in and otu of the front line with an escort chain. Eventually I’ll get it right, too. ;_;
Edit: Also, if/when ‘damage to a module reduces its effectiveness’ becomes a significant factor of gameplay for items other than armour, repair modules will become GOLD. (If a lucky hit reduces your crew module to 5%, a ship might almost stop working, for instance.)
