Darius Ult Refund
Why does Darius get his ult refunded when you outplay him with a champ like Fiora? Blade Waltz right as Darius ults and it dodges the damage, but Darius gets his ult refunded so if you don't kill him while ulting he just R's you again when you are targetable.
Even if you do kill him, he comes back to lane with his ult off CD.
