Th AI is taking precursor anomalies (the heavily defended ones) without a fight. Both the AI (derg) & I had our default starting survey ships next to a precursor anomaly. Did a save and attacked, no surprise i got destroyed, reloaded, passed turn and the AI survey ship moved on the the anomaly and took suffering NO damage. I have seen this several times since the release of merc's, did NOT see it in 1.6 beta without merc's.
