Lunar Blessing - Moonbeams Ignore Shapeshifting Nodes on Swapping to an Uncheckmarked Set

Moonbeams from Lunar Blessing, and likely many other Shapeshifting skills have an issue with mixing up the concept of weapon sets and being Shapeshifted. If a weapon set is uncheckmarked Moonbeam ignores every while Shifted damage node while you are in that set.

To test I fought a campaign boss with my only source of Fire damage being the 8% of Damage Gained as Fire Damage while Shapeshifted node. If the current set is checked Moonbeams scale Flammability. If the current set is unchecked Moonbeams don't scale Flammability.

To clarify: my tree has 8% Gained Fire Damage while Shapeshifted in all weapon sets. Both sets are the same Talisman set to Wolf, so no matter the set I should gain the benefit. This node is simply ignored when you are fighting in a weapon set that is not checkmarked.

The simplest example of this issue: all my attacks are in Set 1, in Set 2 I have Lunar Blessing with Warcry speed nodes. I cast Lunar Blessing with increased Warcry speed, swap back to attacking but because Lunar Blessing isn't checkmarked in my attack set I'm losing every Shapeshift node for my Moonbeam damage. Set 1 doesn't have Lunar Blessing checkmarked in it after all, so the game proceeds to ignore all the Shapeshifting nodes for it - even though I'm in Werewolf form the whole time.

I've seen the tooltips of basically every Shapeshift skill do this - but the long lasting nature of Lunar Blessing makes it a noticeable issue.
