We got a few blackeyes the other day... Part of it was our POS placement (someone, who will remain nameless, placed our POS in one of 2 planets which would not be able to D-Scan the entire system). So we ran some sites and were just finishing up salvaging when our noctis that was salvaging came under fire from 3 stealth bombers, and popped.... About an hour later, one of my corp mates spies a drake on D-Scan and warps off to pop it in an Abaddon, and as he is there, a Machariel, and Loki warp in on him and pop him.... All because we couldn't D-Scan the whole system at once from our POS.
We track them back to their wormhole and are trying to figure out how to get some payback, but they had a lot of firepower, and were fit to take on our tengu fleet (1 falcon, 2 machariels, a cloak fit loki, 2 bhaalgorns, a broadsword, an abaddon, an onyx, a scimitar, and a guardian, and possibly the 3 stealth bombers we were hit by earlier (but we only saw one of them later on)). They lived in a C2 with a static high sec and static C4 (and linked to our same static C4). They didn't have all their firepower in our wormhole, but were keeping some in reserve on the C4 waiting to come in if we started to fight with what they had in our system.
So we look at the mass on all the wormholes and see that their static High Sec and static C4 were pretty low (low enough that we could colapse it with an orca). So we play some stealth games with their guys in our wormhole to keep them interested while we logged on an alt in high sec who had one of our orcas that we got stuck on the wrong side of a wormhole collapse (someone forgot to turn off their afterburners) and start bringing it to their high sec entrance. Managed to warp an industrial with a large mobile warp disrupter to the C4 entrance they came from and cloaked it up (we didn't want to deploy it until we were ready to trap them with the orca collapsing their way home). We had plenty of firepower to beat the guys they had as bait (which was a machariel most likely with the falcon and loki sitting cloaked up on it nearby), and we had the trump card of our thanatos which they didn't know about. But just as we get the orca 1 jump from the high sec entrance, they decide to bug out.... Yeah, it did take 30 minutes to get the orca there, if only it was a couple jumps closer we would have had some nice kills. In the end, we simply lost a noctis and an abaddon. Not the end of the world, since we then made about 1.4 billion isk (total) running sites after we collapsed the C4 entrance.
