I noticed the drones were invincible too, but actually I think it could be better this way to help aiming. For instance, I can try various angles and leads to figure out the difference of each weapons now on a single target, where as in previous versions the drones would fly on until it totally explodes, many times in a flame obscuring vision. Now, I can try some shots, see where it lands, correct aim again, see where that lands.. without having to aquire a new target.
I think this would be good if its given an option too.
