Sif Refactor/Goldencahill

I know some people say Sif is good as she is, since she is only 23 CP, but I disagree. Luke Cage was refractored to be one of the greatest heroes in the game. Why can't it be Sif's turn? I'm keeping her stats the same, but revamping her moves and passives.

Sif - Scrapper

Health: 4/5

Stamina: 3/5

Attack: 3/5

Defence: 4/5

Accuracy: 3/5

Evasion: 1/5

Passives:
 * Asgardian - Immune to Burning, Chilled, Poisoned and Radiation.
 * Dimension Cleaving Sword -  Chance to teleport away from attacks (20% chance).
 * For Asgard! - Attacks gain Desperation when an ally is defeated.

L1 - Thrust L2 - Leaping Slash L3 -  Inspire Courage L4 - Flying Sword
 * Bleeding
 * Tenderized  (Added instead of on L2)
 * Exposed (Added)
 * Deadly Crits
 * Exploits Tenderized
 * Hemmorrhaging Attack (Added)
 * Quick Action
 * Fortified
 * Focused
 * Honed Edge
 * Deadly Crits (Added)
 * Ravaged
 * Weakened
 * Brutal Strike (Added)

So what do you think? Is she too OP for a 23 CP hero? Comment below, I love to hear compliments or criticisms. I hope the new passives and slight move boosts make her useful.
