The "buff" to plea in no way compensates the regen loss from SoI on certain encounters, I agree that it's nice to finally get rid of the healing pentalty, but it's not amazingly awesome, it was just long overdue. If you're smart the regen from SoI was quite substational on many encounters in ToT. Now I don't know all the 5.4 encounters, but I'm pretty damn sure there would've been chances for us to regen there too.
The change to SH is boring, and unless they change the actual mechanic from judgment I can't see anyone taking it. Now, if they'd maked judging itself somewhat beneficial sure. Give it a longer cd for holy, make it give mana back, make it so that we can judge our allies and put a healing spark that increases healing taken for 10 seconds, whatever (just throwing ideas around, thank god I'm not a dev :P). To spend the mana on judging to get one free Divine Light (not actually free since you had to spend mana to cast it) makes no sense unless there is some additional benefit.
They'd have to make changes to SS too, and here I don't know what to do. Have the target of your Sacred Shield somehow benefit more from our mastery? Unlikely since they don't seem to like our mastery >.< Or take the part from old style SS where it'd increase our FoL on them? I don't know. As things look now EF will still be the best, but the best will be pretty piss poor.
