Your stasis field eats his damage, and when Tiberius leaps at you, you can simply rewind him back.

Kinessa can get bulldozer to destroy Luna, and she deals more damage than you at range.

If you go mid-range or short range, Vivian will shoot you down. You're better off keeping your distance. An advantage you have over Vivian is that your heavy blade goes through shields.

If Grohk is using totemic ward, he does have cc immunity against your ult and rewinds, but you can just 2 tap his base totem without buying bulldozer. If Grohk is using maelstrom, your stasis field eats his shock pulse, preventing the spam.
