Golems leaving R&D can create good roleplay, but they always give Security/the HoP/IAA a headache and get the Xenobiologist in trouble. And it's not like any Golem players will ever want to sit in R&D all shift twiddling their thumbs hoping that some bizarre situation renders the preservation of directive four null.
Playing as a Golem can be fun too, but they're restrained from doing much without upsetting most of the people in Security, so I agree that there has to be a change somewhere regarding them. I like the idea of changing them to Cortical Borers, but doing that would give Xenobiologists something that could be used as a griefing tool.
