This mostly does nothing except cleaning up logs and possibly spaghetti code that caused the healing to differ or not work sometimes. There is however one change I find confusingly pointless:
If you have Demon Form active, activating Metamorphosis doesn’t heal you, but Last Resort does… Is the expectation from the Dev team is for people to macro Metamorphosis with a preceding cancelaura for us to get the healing? Because that’s how we will have to circumvent this change.
It would be simpler (especially for casual players) if both Metamorphosis and Last Resort activated the healing, making only Demonic exempt from the heal.
There is enough problems with Metamorphosis being both defensive and offensive CD (for Fel-Scared, same issue that BDK had for San’layn Vampiric Blood, now being patched), this just tosses another obstacle under Vengeance’s feet to deal with.
