Maybe might aura should have a secondary effect?

i would like for all skills to be sensible to not only max but also to use as part of your build. and i dont think “well this merc uses it” means its good enough. players should have reason to use all skills on their trees as they like

i dont think the new devs have touched on might aura yet.
might aura gives enhanced physical damage. but concentration and fanaticism gives more enhanced damage and does something secondary, so they are always better to use. im thinking either might aura could have knockback (which is circumstancial and there is already smite for that) or it could have a tiny increase in chance for crushing blow, that could increase one number per level, so 20% chance at level 20. or maybe 10% at lvl 20. i just imagined an army of necro skeletons doing crushing blow. though it also begs the question if concentration could need a second look not to become the next unused skill

a second thought to might with knockback, maybe it also gives knockback to spells?
