I wouldn't care if they stayed or go
But Vercure does make PotD possible to solo with RDM and its decent for a dual cast proc when boss is away so it has its uses
Clemency is just more button bloat for Paladin yeah it can save a run on occasion and its nice when your healer just completely ignores divine veil so you proc it yourself but its not needed but if it went would like a sustain tool to replace it
