Meh, maybe 6 power cost but 7 is pretty spendy. Cyborg Eddie can possibly steal all enemy buffs and heal himself per buff with his basic so it's like a moderately better version of Astra's attack.
She can't stun you if you have any immunity, plus having immunity cancels her nasty power move. And any shield ever usually reduces true damage, plus everyone has a Golden Pharaoh Dog to reduce damage. Plus Exhaust is becoming slightly more popular. Plus you can cancel her passive with passive disable, or just kill her first.
I'm not trying to defend her hardcore, but she's not AS broken as she used to be. I haven't used her in PvP for a few months now.
Oh yeah, and angel talismans are a thing, so the only real thing should you not have Immunity and get infected with her power move, is perfect corruption.
