I am creating this thread to continue the exploration of issues related to Drone Weapons upgrade and particularly the critical issue of the cost effectiveness of upgrading the Drone itself versus upgrading Drone Weapons.
There have previously been discussions of this issue and other Drone upgrade issues in various other threads including the Micromanagement and Green Glow threads and I recommend reviewing those threads if you are interested in issues related to Drone and Drone Weapons management.
I acknowledge the valuable work done by others on this chat, including Scorpion (Amsoft2000) and NK2014, much of what I summarize here is taken from there work on the subject.
Also recognize that the Drone Weapons upgrade program was broken for several weeks and so I have no experience with weapons upgrades at power levels below 51K. It is, however, my belief that below 51K Drone levels, players should concentrate their efforts on upgrading the Drone to 51K, and not devote any Diamonds to weapons upgrade. If you have a differing opinion, I would love to here your insights.
