I got my self feeling I open Request Depots, set to 10 Drones request - 100500 times...
I suggest adding a map (or/and per player) setting "Default drones count" - so that when a requester is built instead of 0 (zero) that many drones requested.
Requested by logistic bots or dispatcher depot? (if logistic bots i'd suggest to start with a builtin predefined logistic group) but yes there's space for improvement here
