Been testing on the PTR, and my doomguard appears to be hitting between 39 and 48% less on average than live. It's most noticeable with chalice procced and necromantic focus at full stacks, which suggests it's the mastery scaling and not the base damage?

Anyone have any ideas?

In 4.3, we have fixed the bug that caused the Doomguard to benefit too much from mastery. We have buffed Demonology warlocks to compensate. Also note that we have not yet completed our balance adjustments for 4.3 so what you've seen in the patch notes are mostly of a mechanical nature.

That said, we think balance is in a good place overall, so anyone expecting huge pendulum swings will probably be disappointed.
