Some good ideas here, but I'm always reluctant about changing too many things with one unit's balance at one time. That tends to lead to radical swings, a unit that is superpowered one moment and completely trash the next, then a superpower again, etc. At the moment the change is on the AI side only with regard to the 10% chance only of reclamations, and then on the human side with the hard upper cap of 1,500 per mark level.
Those two changes alone ought to have a pretty striking effect in and of themselves, so let's first make sure that shredders are still even OP after that stage. I suspect for the AI, they will not be. I suspect for the humans, they may be, but by a little bit. But I've been surprised before. So let's just give that a bit, collect various opinions on the revised shredders in practice (not theory), and then let's theorize about how we can further optimize the already-revised ones.
I really appreciate all the great ideas, though, and they provide a lot of good starting points for further optimization with these if it turns out that is needed. Thanks!
