I remember the fun times with people yelling 'BK' in the guild chat, and we all joined in and murdered the poor fella and froliced where it had fallen. It was better, but I still think they easily could have fleshed it out more.

What if they made a custom gate in the arcade during the Kataclysms with only floors that black kats can spawn on?

29 floors of only black kat hunting.
And you could bring your friends along too.

Maybe a chance of a bonus level at the end with a doubled spawn rate of black kats if you go from 0 to 29 in one go?

That and either increase the drop rate of pages at elite, or decrease it at lower difficulties.
