Hammer of Wrath + Blood Angels

[eMarchenko]

Found a problem for Assault Intercessors With Jump Packs in Sons of Sanguinius/Liberator assault group detachment:
Their ability Hammer of Wrath gains additional attacks, i.e., it rolls 10 d6 instead of 5.
Personally, I've marked the ability (modeled as a weapon) with EXTRA ATTACKS keyword of Unitcranch, which resolved the issue.

I guess it is a rare combination of rules that affect only few models
From the top of my head I can only name Brutalis Dreadnought.
Overall, it might be beneficial to mark unique abilities as EXTRA ATTACKS to limit unwanted rules interactions.
