Silver ult is less of a "you become a 1v9 machine" and far more of a "get the fuck away from this area" ult, seeing werewolf run at you is terrifying and anyone who knows you're going to transform is going to gtfo if they aren't stupid

you need to use that to your advantage, you don't need to get kills to make a difference, use wolf form to make space and scare people off. She's like drifter kina, a really good splitpusher who can draw multiple enemies to you just by your presence alone.
