Help! I need some advice.

Iíve written a fantasy novel about divine Avatars. The ones from mythology that become the vessels of gods.

I recently received a critique that suggested I come up with a new term for them, since the concept of ďavatarĒ is currently so overdone- with The Last Airbender and the James Cameron movie.

Do you think this reviewer is right?

Thanks in advance for your opinion!
