While I agree it's frustrating that you need a specific job to be filled for something in a round, that's the nature of the station. Science needs mining. Orders need cargo. Robotics needs RnD. Staff changes require HoP. IPCs/Borgs require robotics for repairs. Etc. We make do in these situations, and sadly without a properly staffed med bay, we must make do without cloning. This isn't a terrible thing, as nobody should depend on it (Staffing aside, Abo raises a ton of points on how cloning could be prevented, and that's not even exhaustive).
There's legitimate reasons to take a hard look at cloning. "Antags kill people" is not one of them, which is why I'm being so critical of this thread. Maybe we should revisit the trauma system which drove away many psych players in the first place, or ask ourselves if there are other reasons WHY the role isn't often played.
And I certainly agree that forced conversion to an antag is incredibly annoying. But, again, that's the nature of the round. I hate vamp and I hate cult, and I hate playing those roles, and I totally get where you're coming from with being forced into them. But again, the round isn't just about what I want, and I try to make the most of it (barring shit antags like wordless thrallers). If you don't care about the antag's story, or other players' stories, why should anyone care about your character's?
I honestly wonder if Aurora is the correct server for you.
