From my own experiences, it felt like once I upgraded some of my gear from Prestige 6 to Prestige 7/8, the my healing values were in the same neighborhood as they were before the adjustment. Then I started getting PA levels, piles of cheap consumables, more valor, and everything went out the window.

If you use divine call to proc serendipity you can spam HC at 0.5 like mad since it will be
0.0: Divine call->proc serendipity
1.0: ICD ends
1.5: Cast HC
2.0: HC casts, ICD starts
3.0: ICD/GCD end, cast HC
3.5: HC casts
4.5: ICD/GCD end, Cast HC
5.0: HC casts
and can cast 0.5HC til you run oom.
but just the fact of using a 1sec+ spell to proc the first serendipity, it screws up the whole ICD rotation and you miss procs
There is no global healing nerf applied by the game.
The patch note would read something like Healing Spray: Now heals 70% of normal in PvP, previously was 95% (example, I dont recall the exact numbers, but it was never a 50% nerf)

You can play WoW in any MMO. You don't have to play WoW in RIFT. Oh, and no, RIFT is not a WoW clone. Not having fun any more? Learn to play, noob! I don't speak for Riftui, but I moderate stuff there. Just came back? Welcome back! Here's what's changed. (Updated for 2.5!)
Looking through the data, and cross referencing Vs the list of nerfs in 1.4 (from the handy dandy patch notes section), I'm unable to find anything that was hit for more than 10% at that time. If you know of something, please let me know so I can double check the data.
