So, the patch notes for 1.5.4 read
But this doesn't seem to be the case. I agree "much less" is not specific, so maybe my threshold needs adjusting, but if the intent is to make them more viable a threat, I don't think it's working. Here is a screenshot of a engi cruiser with 3 drone defense drones in addition to the defense 1 (it's hard to see the 3rd one). This was taken on Hard difficulty, with AE enabled.Bug/Misc Fixes:
Enemy ships are much less likely to have 2 of the same drone.
I see two of the same drone pretty often, and 3 was just too much. I realize it's random, but given how little I play the probability is astronomical.
