Some of the Dragon's in the game are listed as "Level 4" or some such. This might give the wrong impression that if you're level 4 you'll be able to fight it and win.
Which is not the case.
Maybe make monster levels the same as the CR in the books?
100% agree. They need to stick with the 5e core rules as much as possible. I don't mind them homebrewing here and there, but the core ruleset should be there.
