Not gonna say anything about durability just yet, since I haven't gotten an opportunity to test that properly.

• Please add roof elevators to the Command Center and Rebirthing Matrix spawn rooms.

• One-way shields are good. Please return them.

• Old modules are seemingly still in the cash shop. To be patched.

• New structures are cool, but some are frustratingly sensitive to terrain level. Would be neat to have more options to make outposts in unusual spots, possibly some sort of raised foundation structure that has a slot for one structure on top of it (such as the rebirthing matrix building).

• New module system is actually really cool architecturally, but I'd like to see the Skywall Shield and lower-tier repair split off into separate Spires; a Skywall umbrella evenly encapsulating the base is preferable, and having to carry a repair module to every single structure you create will get tedious very quickly.

• Big one: Temporary modules' lifespan should be based on usage, not time since installation. Heavy Repair Module's lifespan only ticks down while repairs are actively needed, Fortress Shield Module activates on demand (press activate key on the installed module) instead of immediately on installation, and Heat Dispersion Module only expends its lifespan when the turret is firing.

• I'd like to see a finite "Deterrence Module" that emits pulses damaging enemies in a fairly large radius a la Pain Spire, decreasing in durability based on how many enemies were hit, as a new tool to keep smaller skirmishes from getting highly frustrating.
