I gave up on being player for that game, going to GM (they liked the ship build though and wanted to use it).
In the future I will give the group an endeavor in Naduesh for finding upgraded archeotech las emmiters for upgrading the macro-batteries to Best Quality.
I agree it's not fully a "killer" build, but it's a certainly a fun and flexible one to play (why send an envoy to Ansai if you can just invade his cities, "replace" his citizens with imperials, build water extraction pumps and enslave the priest kings themselves into become "luxury resource pumps"?).
