That's why there's three tier levels to choose from. Low will give you characters who engage in more traditional combat, swordfights and gunslinging and the testing of strategies. Intermediate will give you some of that, with some of the benefits of epic-level powers to play around with as well. High will give you purely epic-level powers and the destruction of entire cities in a single fight. 

But a high-tier fight could easily have a better story behind it that a low tier fight, or vice versa. Power levels have nothing to do with the quality of the writing, only with what kind of writing you want it to be.
