The Ult is good but Defend comps don't have much room for her imo. The rest of her kit doesn't seem particularly strong for defense.
She can definitely see play on KoTH/Attack and any place you are going to be aggressive.
I disagree here. Her entire kit is based around dismantling wombo combo and that is generally why 2cp is so lame because the offense just has to wait on their ultimates to come online and then win.
