In agreement with Tonuss, take these patch notes with a grain of salt. I would deem these changes as highly unlikely.
I used to get concerned when patches and changes like these happen but in the end it all works out, and there are way too many fake ones to filter through. Past that even when Blizzard releases the patch notes, it has to generally be accepted by the community or they fix those as well. As can be seen with the last patch that attempted to nerf Lightning Bolt and Chain Lightning, Shaman community revolted and they reverted the change.
