That's fun story stuff, so thanks for sharing it!

Currently Battle only requires 1 kill to get in as far as I'm aware.
I think Fort squires require 1, under the idea that your job is to kill evil so show me you CAN kill an evil. I'm not Mr. Fort, so I can't speak much beyond that.

I think I can agree with your general sentiment that it neither breaks, no provides much for, the system itself. But I also don't think the 1pk requirement is a big wall for casuals. Even when I rolled my first rager I was able to get a pk, and it wasn't a "high number" thing. It took me a week or two, but I did do it.

Decked to hell... For shame, I thought we closed hell! :P

That's good food for thought though, thanks for sharing :).
