It has a cooldown so you can't constantly revive like other medics.
And let's be honest, how often will the fact her revive is AoE going to benefit the team that much? The radius of it is pretty small and usually if you are able to revive 1 person you will revive the other one as well as any medic.
She just doesn't feel like a medic. You can't have her solo medic because she is not a healer and the cooldown on her revive just makes her feel as a disadvantage. I honestly would rather just have an engie with that active defense drone (idk what it's actually called I'll just call it ADD) so I can stop worrying about grenades while repairing.
So please, just make it so her revive also heals teammates in it's range up to 100hp - the amount of health it heals will be the same amount of health as a teammate would've been revived with if they were revived instead (except Get Up would have no effect on the healing).
You can increase the cooldown and lower the self-heal amount if she becomes too strong. But don't leave her unable to heal
tl;dr: make her revive ability also heal
