Thanks again for the detailed feedback, you were right on every point, and 1.3 is live now.
Ammo is actually consumed in combat now, so it's a real resource you have to manage. Fortifications no longer make you invulnerable: even fully dug in, a position takes losses under a heavy assault. And reinforcing an already well-fortified position costs a lot more. The persistent recon bug is fixed, and the Cricket can now spot enemy batteries in the area it flies over.
I kept the AP count at 5 for now, with ammo actually mattering, the tension comes from the resource pressure rather than the action limit. Curious to hear how it feels on your next run.
Thanks for your help
