I've not scored chain trippers badly on power ever. I HAVE scored them low on originality.
For reference, here, have a definition of originality:
"Originality is the aspect of created or invented works by as being new or novel, and thus can be distinguished from reproductions, clones, forgeries, or derivative works."
A chain tripper is not new or novel. See my issue with it yet? Same thing with a pure Craven sneak attacker who does nothing else, or a supercharger who does nothing else, or a Giamonk who does nothing else. I score them ALL low on Originality.
