Troopers have a companion that uses a techblade with aim primary stat also (IMO he's the best companion to use for a DPS or healing commando). So it's not like this is a unique problem.
Oh I know, Troopers aren't even the only other one. Smugglers get Akaavi too who has the same problem, and the Imperials have their own mirrors. That's partly why it's really dumb. BW has all these companions now that have itemization problems just because they wouldn't make the graphic of strength armor look like trooper/BH armor when worn by certain companions.
