I remember the bladeweave phase that many went thru.
Cold Wind and Angry fire do nothing.
Crushing blow does nothing.
I never understood the bladeweave phase, didn't make sense even on paper to us.
Angry fire does do something... is it worth it? No.
Crushing blow, does do something, though from what I recall on testing, don't have my spreadsheets, doesn't get the damage boost.
Problem is when it comes to dps, few abilities/magics shine. And those change slightly if you can get something with 10 or less resist I the pets damage type.
Crushing blow is merely a utility ability, like many of the others. In a game where nearly all encounters don't need the utility.
