I am so upset about losing the drone fully updated after the latest system update. I know that the latest system update has removed the drone, lifeguard, that I had been using for my tank. Then, don't you think there should be rewards to compensate for my loss? The GS of my tank was the mid 9000 and is now mid 7000. How ridiculous it is to simply remove the drone without any rewards or actions to make up for my loss. I am seriously thinking of leaving this game that I have been playing for a few years.
