So I think the wording is clear, but the picture is contradictory. When a worker that has a claw component attached displaces another worker, can they only displace opponents? Or can they also displace their own workers?Note that there are no "blue" pieces; "blue" in the rules refers to a generic worker (as evidenced in the Symbols list in the rules, where a blue worker icon refers to "a worker, normal or upgraded.")
The wording says you can displace opponents, but the picture example shows a Blue guy displacing another Blue guy.
The rule wording is clear, and confirmed on the player mats: claw workers can only displace opponents' workers.
