Not really. You can start it at level 44. If you want to level up some more and make Celestia easier I'd suggest that now is a good time to work on Wintertusk.
I was wondering if i was a low level i am a 51 who just started Celestia.
Your level is fine. You used to have to be level 48+ and now it's even lower. If you're having a hard time, try doing Wintertusk to level up fairly quickly
