I'm on a new server (less than 1 month old). While the old one is plainly impossible to kill anytime soon; the new nerfed one does not even live 5 mins. The nerf is far too drastic.

If you couldn't kill kyuubi in 40 mins, you will now get about the same reward for pawning him in 5 mins. If you did kill kyuubi in the old system, then you get much less rewards now.
