I object to this. I see nothing inherently wrong with something that may just so happen to allow a user to "fight good" so long as it's original. Same goes for things which may just so happen to be able to "fight good," as long as they're not just another SCP trying to top Able. I think the same can be said for most of these things.
I don't dispute that totally unoriginal SCPs are crap. I dispute the idea that a SCP's good properties are rendered moot just because they posess a property used before in a different SCP.
(for the record, I'm not just saying this in an attempt to defend 472. I acknowlege that 472 is crappy in its present state and I hope to fix it in the future.)
