I wrote up this to put on mantis but then i didn't because I figured that parasites break the game anyway, so its not news when they break specific parts of it.
I did find you could hold a superterminal open indefinitely with leech starships and a decent amount of defenses.
Specifically exploitable is that the superterminal will spew out mk3 scouts when its in in mk3 phase, as well as rare buff ships like armor boosters.
Shield bearesr in particular break the superterminal because a big stack of captured ones will soak all the damage from a wave.
If I had my druthers i'd give the superterminal (and Eyes) a reclamator protection aura.
I also believe the superterminals arnt scaling with ship cap but i havent tested that.
