Yes -- Another one of these threads lol.
Fact...
The top mythic holy priets such as Malivis are running 2pc t17/2pc t18
Mr. Robot even shows 2pc/2pc as BIS ><
Opinion
I personally don't like it and my numbers parse great using the 4pc t18. I don't consider myself top end by any means.. But I do Parse fairly well.

Below is an Iron Reaver parse where I was using the t17 2pc. I have even shrunk the size of the fights so it only shows the first 3min 30s.. I got off 12 POM casts for only 72 bounces. That is 6 bounces per POM cast.

Below is an Iron Reaver parse where I was using the t18 4pc. I was able to get off 10 POM casts for 143 bounces. 14 per POM.

I know I didn't take into count Words of Mending. But I'm not sure how to calculate when WOM produced a POM stack.
In summary, i think its the RNG of the 10% bounce is what scares the top end holy priests. They would rather have the guaranteed extra 4 bounces. I personally think the extra stats (10+ ilvls) accommodates any bad RNG
