Basically a money saver for DM's, when a drone gets destroyed in battle it drops fragments for that type of drone that can be used in a bp to build back.

There would be different bp's for the specific types of drones, bp would require the fragments (maybe 4, 4 could drop per drone) and money depending on what drone ur trying to rebuild.

Maybe you should search before suggesting this, been suggested >10 times already. Not going to happen, drones are expensive for a reason as devs said countless times

Don't foresee it in the near future. Something may happen with drones eventually but if/when we come to a decision on those we'll announce it. As mentioned above, plenty of other topics on this suggestion.
