Risk/Reward after you get the drops you need for the hyperport is non-existent the modules scrap for junk ctp and the research module is useless once you are big enough to to take down hyperports. 5% chance at +50 attack for the base is not enough incentive to drop the amount of energy required to lock it. All other high level npc's at least are worth hitting or not bothersome. I would say either up the amount of ctp the items scraps for or give a level appropriate reward people would be willing to dump energy into it for a chance at getting something good.. How about changing the hyperport networks to something like size 1 research 1 arti 1 def 200 cloak 200

Nexus - Cache
Hypergrid - cheap to lock for moderate to low ctp
Kelethor - ALOT of schematics to find and the planet arti is good
Hives - cheap to lock for moderate to low ctp
xrp warp station - warp fuel is a good drop and worth the lock
Telarys - cheap to lock for moderate to low ctp

The planet structure is alright but we really don't need research on our planets now
Just put a little cloak on the structure and you won't hear a complaint.
