Darius and new rune system
Honestly I cannot see any use from it on him. He was really good with Fervor of Battle cuz it allowed him to build BC + 5 defensive slots without losing too much damage. The worst part there will be damn "hit enemy 3 times and you will get stormriders surge". Damn even more mobility for kite-poke champions... Grasp of the Undrying? Nah. I just can't take this mastery serious after Fervor of Battle.
