I love the ways the ability icons are themed to the hero’s aesthetic, or even have their own unique aesthetic.
Ogre’s icons are scrawled, and Primal Beast’s look like a cave painting. Spirit Breaker’s are shaded like graffiti, and Lycan’s are reminiscent of comic books and even TF2. Bane’s Nightmare looks like a weird brain thing but is actually a burlap sack around someone’s head which is frankly way scarier.
So many of them have a ton of personality and I appreciate that. That is all :)
