Signet of Restoration has a passive effect that heals per cast. With written in stone it should maintain the passive effect even when Signet of Restoration on cooldown. But what I found out is that when it is on cooldown it heals less per cast spells.
At 80 the Signet should heal about 202 per cast spells from the passive effect. This is without +healing from trait/gear. But when you just trigger the Signet for the big heal the passive effect become less potent dropping it to 150 heal per cast spells.
Is that intended to somewhat nerf written in stone trait? Or is it a bug?
