Vercure is not part of your rotation.

[GospelVhae]

Late to the party but while I condone using Vercure in general

Vercure is NOT part of your rotation in the same way that Second Wind or Bloodbath aren't part of a Melee DPS rotation.

Comparing a GCD (Vercure) against Second Wind and Bloodbath, both oGCDs, is not a fair comparison. Yes I'm guilty of using Second Wind and Bloodbath because I weave those in between GCDs as a DRG when I was progressing A12S on min ilvl, usually on the Prey mechanic
