Think that all you want.
Nano-Boost is only getting stronger with one less player to peel and punish you. Anti-Nade still exists. Sleep Dart still exists as the ultimate “Shut down 95% of all Ults”. And now she will be highlighted as one of the best DPS supports in the game instead of a tank healbot.
All it will take is a few weeks to solve how and where to position with her in Push, and in 5v5 and she’ll be right back on top.
