In terms of pure telepathy, I don't think anyone is much ahead of her. Jean had high end telekinesis as well, so was overall more powerful, but Moondragon has telepathy feats very much on the very top end of the psi record.
She has simultaneously mind controlled an entire planet, for example. When Drax the Destroyer (her father) resisted her psi and was going to battle her, she killed him, using her telepathy to render him brain dead...and yes, he was herald level at that time.
Bottom line, with no psi defense, she could well be a team level threat.
from Captain Comet, potential protection from Forge, etc, so its not as likely to be such a decisive factor.
I wouldn't worry, you're winning as it is...
