Question about core zenith reserves? (worth and effort?)

[TheStratovarian]

I started a new one, facing a sledgehammer and fortress baron (It loves picking that one for me, despite options of medium ones) And I've four area's that i plan to hit to give my home station free breathing room. but right next to one, 1 hop away, is a core zenith reserve sitting on a mark four world. With a whopping +90 ai cost, is it always worth it to claim it?

Oh, quick other questions, but will a mass driver fire on a dysun sphere?
Can an ion cannon kill dysun gatlings (since it doesnt seem to have instant kill immunity?)
And is there any way to coerce the traders to visit a world so if either of the above are true, i can remove it. (but dang, I've seen some gatlings 20+ worlds away helping me. Those things are amazing how far they travel.)

Save it until you really need it.  I love having those around, but never break them open until I meet a planet I need their help defeating (they could help on defense, too, but since the energy burden would probably cause brownouts for your force fields, that would be of questionable help there).  When you hit a planet or planets where you need their help, you will absolutely love these.  But given the cost in AIP and energy, it's best to just keep it on tap until you actually need it.

No, it's absolutely impervious to... everything.

I believe they are mark V, which means they'd be too high level.

And is there any way to coerce the traders to visit a world so if either of the above are true, i can remove it. (but dang, I've seen some gatlings 20+ worlds away helping me. Those things are amazing how far they travel.)

The traders are entirely random, and don't pay attention at all to what you do -- sorry!
