Would go into captivity put a hero in raiders camp. Some people i have asked said yes and some said no.
I think that the reason for the discrepancy is the fact that
Go into Captivity requires that you have a warrior-class EC in battle. However, that is only a trigger. The EC is only capturing a hero if the SA on the character, or on an enhancement played on the character, are causing the capture.
I view it as an enemy in a movie luring the hero into an ambush. The main enemy is running away, not fighting. Once the hero is led to the ambush site, there are other enemies who do the actual attack and capture. The main enemy then just turns and laughs, then begins his monologue that is just long enough for the hero to find a way to escape. So, the main enemy did not actually capture the hero, even though he triggered the ambush. The hidden enemies performed the capture. Likewise, your WC EC triggers the capture, but GiC actually carries it out.
