What if I max Maul instead of HOW? I know my pets will have reduced killing power, but honestly I'm more concerned about my killing power--the more the better. slvl 20 Maul with fully charged 260% damage is superior to HOW's slvl 20 153% ED (and the AR is better for Maul, too).
I like HOW (it especially looks cool with that red aura below your feet) and had it maxed on another build a while ago, but I hate how it dies in a snap, and you have to recast it over and over again. It's annoying.
