Need to destroy gates in systems I take?

[ckessel]

Subject more or less covers it. I know I can raid to destroy a gate to keep that system from warping guys into my nearby systems. My question is, if I take over a system, is there any need to destroy the gate in it or can I save the +10 piss off the AI points and leave it alone?

You can avoid destroying the warp gate if you wish, but as long as it exists the AI will still be able to warp raids directly into that and adjacent planets despite the fact that you control them.  If that's worth saving the +10 to you, then go for it.
