That is true. You can infer what is possible in the game-universe by looking at their spells and skills. That is quite fine and I actually do it a lot.
But I ask: what lore do character levels entail? There are some mechanics that are only constructs with the intention of creating gameplay, not lore.
I wouldn't try to infer the in-character power of someone by looking at their level. It doesn't tell me anything, character-wise. It only tells me the players has time to play.
Communication and common sense is what solves most of problems with 'power levels': don't go around making shows of incredible powers in the street to any random passerby. Save that for when you are acquitained and are relatively sure they won't mind you casting a meteor on their head. Or even better: use the common sense and consider why you gave your character the ability to summon meteors out of nowhere.
