The tanky perspective can only stack to 60 tops, unless the target dies be4 it ends. 60 Ar and MR is just to keep you alive while you get out.

20% is only after 3 consecutive hits on a champ, and this damage cannot crit (balance purpose) In a teamfight, your ulti will not benefit from this. This is an early game passive so that fiora can get a small edge, be4 falling in mid - late game.

As a fighter, Fiora does not excell. But this rework will make her good as a bruies, because of the 60 bonus defences.
