I just checked the Known Issues and Patch 14.1beta-notes and didn't find anything about the Healer's Friend-enhancement.

As Tolero mentioned here and here "some" other bugs will get fixed in 14.2 but as the borked Healer's Friend is not in the Known Issues-list I am a bit scared, that HF will be mentioned in the Patch 14.2-notes as working as intended giving no healing amplification at all...

Please proof me wrong!
