This will be nerfed soon I am sure as well. It's an unintended thing and after the chain stun nerf I'm positive they do indeed read this forum.
This is a bug that needs to be fixed. As far as the chain stun bug, everyone seems to be excited about the idea that the sky is falling. It is a bug, JChan has said as much (discussing it in the patch bug thread). Its not a nerf, its an accident.
