Unless I'm missing something this change was from an erroneous patch note during PTR. Even on the PTR I don't think HS ever procced SH and the tooltip was reverted back before live.Selfless Healer: The talent now procs from Judgement and Holy Shock making it a nice passive bonus for single target healing. Every 3 HS casts you will be able to cast a free instant super charge FoL. If you don't want to mess with the HoT and shield mechanics, this may be a strong option.
Maybe you should also mention that EF now does double healing when cast on ourselves. It's a very strong HoT leading to crazy mastery shields and strong beacon transfer.
