Also, does crushing blow / death strike work with Bladestorm? It appears that "on melee strike" procs do work when attacking with bladestorm, but I'm not sure I ever saw CB / DS work...
There are spells, there are summons, and there are wdm (weapon damage modifier) abilities. Weapon damage modifer abilities (anything that causes an attack animation, and will say something on the tooltip like, '85% of weapon damage converted into X') are directly affected by your weapon damage. They don't double dip into spell power. They do, however, benefit from elemental pierce. Stormblast, an ax ability for barbarians, actually has pierce built into it.
Blade storm and moonstrike both have weapon damage modifiers.
