Enchant for aoe/adds bossfights

I’m a dual wielding human fury warrior, however, for boss fights with adds(MC snakes) I switch to my 2h axe Drake Talon Cleaver, i know that it’d be better if i had a mace/sword but i don’t :(i’m wondering what should i enchant my axe with? Was thinking of crusader by default but maybe the +9 dmg enchant would be better? how about fiery? would it be able to proc on all 4 targets of whirlwind?Crusader proc is rng and i think that fixed +9 dmg on aoe is better, but may be wrong :)Opinions?
