If you look at her 2 rounds of undying passive description,its possible to remove the buff at the beginning of battle.With out current meta based on position 1 i don't think she will have that much impact on our server.

Her kit looks good on paper but can she survive,blast by full power Kakuzu in round 1 perhaps she can if shes in position 2.

Nowadays your pos 3-4 will die or left 10~20% after Kakuzu's blast in round 1,but then again not everyone and their mom use full bt Kakuzu or Ronin Naruto.
