Well, they don't seem to like the taste of Imp Slaves. At least the Thargoid I came up against didn't like impi's.
BTW, the impi slaves said they wanted to be abducted by aliens, so I was cool with ejecting them as bait. I already had got a TP from a different system just before this encounter...
I did use chaff, ejected some impi slaves as a distraction, twice, but Mr. Thargy wasn't buying it. I was going too fast and damaged the TS, then destroyed it on the second attempt. All while being shot at by the Thargoid. I am lucky I did not get EMP'd. I think chaff, pd's, and the 4D HRP probably saved my life, or maybe the most effective part was having my high wake already plotted/selected.
Next try will be with occupied escape pods as bait. And better shields. And an AFMU with hull repair limpys. I guess.
Also, doing something involving Thargoids after not playing for 3 months is not the best idea. I was
rusty as hell.
