Actually, flooding the system with ships is the way to go, with an emp leading the way.
For whatever reason, hybrids hate scouts, when the emp takes your friendly scout's cloak down, the hybrids always chase that out of the system until the emp wears off, giving you time with your main fleet when you warp in.
Having said that, I warped in, destroyed the cloaked guard post on the warp point and a Short Range guard post that was close, then got out and only lost 1200 ships or so I think.
At which point I said screw it and nuked the system. AIP will be over 1k as it is, 50 AIP doesn't matter at this point.
Except the nuke didn't work as advertised.
It did pop the command station so the hybrids are leaving, but none of the hybrid fleets, which are all Mk III or lower, were destroyed by the nuke. I did expect the hybrids themselves to survive, but this is 10k or 11k ships that survived that should have been destroyed by the nuke.
As they weren't, I'm not sure the nuke was worth it, effectively all it destroyed was the AI Command Station.
And I'm done messing around with this. I could break the system, but it would take me 2 to 3 hours of gametime to do so. (I guesstimate anyway.)
