Was the CoS nerf akin to Ony's Deep Breath?

You old school WoW players know what I'm talking about :P every patch theres mountains of anecdotal evidence pointing to stealth nerfs, but nothing to really confirm it.

All day the US boards have been full of people citing a small sample of tests done by a EU player seeming to indicate a massive nerf to CoS. If you don't believe me and feel courageous, go check it out :P

However, now that the US servers are (finally - I'm still patching) back up, we're getting reports of CoS being fine and just how it used to be. So, what's the deal? The tooltip for Cyclone of Razors has certainly been changed from 28% to 10%, but some people are claiming that this was simply a display error that was corrected (wouldn't be surprising) and that we had always been getting only 10%, thus, no nerf.

WELL???? What are you seeing?
