Hi All,
I wanted to take a second and clear up any misconceptions about the nature of this bug fix. The Runeblade of Baron Rivendare neither scaled with +healing nor snapshotted any +healing effects in Original WoW or the 1.12 Reference client. This behavior was a bug that was introduced into WoW Classic. As such, the fix that went into 1.13.3 that removed the +healing benefit and snapshotting restored this item to it’s original 1.12 state.
As this bug is now resolved we will be closing this thread now. As always, thank you for your reports and analysis!
