I propose the scrap to 18-38 like other modules. I don't see the reason why the advanced version of Dark Defenses yields lesser CTP.

(or that's maybe it's an advanced version, because it uses less complex parts for better defense )

EDIT : and just noticed that Silthion Utricle too... Why more advanced modules grants lesser CTP :O ?

Because you can get loads of them...

Dark Phase Engine (Uses Left: 35)
Dark Anti-Beacon (Uses Left: 41)

At rank 435... that means I have 1565 ranks left of getting these.

Yeah, pretty much what The Prisoner said. You can see the NPCs that drop the better mods for a longer period of time than the ones that drop the lesser modules, therefore allowing you to get way more of the better ones. If they scrapped for more, then we'd all have level 10 bases...

Meh i'd still like to see these net more ctp even if they are more plentful it does seem annoying that the higher rank and tougher the npc the less the ctp things scrap for seems kind of backwards.

If more ctp is introduced it will just change the ratios that it gets traded for.

Ctp will always be in demand regardless and seeing as how it's had 500% increase in price in the last year or so i don't see this as a bad thing.
