First of all this doesn't help her in the Deathstroke MU. Second of all Catwoman doesn't really need buffs. She already vortexes up the ass, her meterless damage is stupid high, she blows up Superman (catstance makes his F2 whiff. He literally can't do shit @ footsie range when you're in that stance. If he does f2, you can press 1 in catstance, then b3, f3, etc. into reset. He can't keep her out either), wake-up trait is invincible & she has setups in the corner that force the opponent to wake-up backwards.
If you buff Catwoman significantly she would be the new Flash.
