I'm extremely disappointed with Zenith Reprocessors.
As a pure fighter, I'd be happier with about twice the cap, they don't compare that favorably to acid sprayers or even fighters, even going against bombers. They interested me because of the firepower/individual unit ratio, and perhaps taking down Spire Shield Posts and unshielded hybrids fairly quickly) but I'd rather have more specialized units such as Stealth Battleships or even Spire Medic Frigates. Some testing leads me to half-believe they don't even reprocess anything at all, I just haven't thought of a way to set up 0 income/second yet. Now as the note clearly spells out, they can't reprocess things that are immune to reclamation, such as zombies, guardians and guard posts (high value targets), but using nothing but them to fight bombers or missile frigates leaves me in doubt as to whether they work at all, or just offer so little return as to be confused with the economic power of two star systems on a 3 champion, 3 homeworld co-op game.
Now obviously, allowing them to reclaim an ion cannon would be well overpowered. I would also need to figure out a high resource, non-reclamation immune unit to test them against, If I cannot figure out net zero resource gain.
