I am a level 46 master I just finished The crucible and I see people way high leveled then me (people in level 48-52) And I wonder if I am under leveled?
As long as you're enjoying it and managing the battles then you're fine! That's a nice level to be doing it
When Dragonspyre was the final world the max level was 50...so that gives you a good idea of levels. As there are lots more worlds now it's easy to be a little above or below that by the end of the world.
Just a heads-up though...there is quite a jump between Dragonspyre and Celestia. Some of my wizards struggled with the jump and went back to do Grizzleheim and Wintertusk first...now I just do them at that point without checking if I can survive lol
You might like the quest trees if you haven't seen them yet. They're great for checking out what side quests along the way are valuable ones (eg spell quests or training points etc). You can find them easily with an online search: W101 [world name] quest tree
