And for the same knowledge cost as well. Both the econ station and metal/crystal mark harvesters cost 9000 knowledge (mark II + III).
Oh yea, they have no cap but are still balanced and knowledge costed to the same degree of something with a cap. That is another factor as to why Mk. III harvesters seem OP right now.
Oh yea, and the fact the Econ stations have an opportunity cost (if you use an econ station, you don't get the benefits of the other station types), but harvesters don't, but they still give the same average rewards per new planet.
I vote for a cap. Right now mark I/II harvesters are useless when you have mark III harvesters while every other mark I ship in the game never loses it's usefulness (well, on 60-120 planets at least).
You mean like having a cap for Mk. III and Mk. II, but leave Mk. I uncapped, like we do with the command stations?
Yea, that could work, but one, what is a good cap?
IIRC, the cap for MK. II stations is 6, and the cap for the Mk. III stations is 4. Thus, if we want to keep the parity with econ stations thing going, that would mean Mk. II harvesters would have a cap of 12 each (avg. 2 harvesters of a single type per planet * 6 planets), and Mk. III harvesters would have a cap of 8 each (same, but * 4 planets)
The caps may need some fiddling to properly account for the larger number of harvesters on homeworlds (like add an extra 4 to each cap or something)
One, this would complicate auto-harvester rebuild logic and auto-harvester upgrade logic (where do you want your Mk. II and Mk. III harvesters when you unlock a new one, how should it choose?)
Two, this would remove one of the distinguishing factors of harvesters vs. econ stations
