That’s the point. If you want everything right away just start with max level characters. Congratulations, no more leveling up means no more agonizing choices.

And no, having a more powerful character at level X doesn’t change this. It just means that either your DM starts throwing comparably more powerful enemies at you or everything gets easier. In the first case you’re accomplishing nothing because everybody involved is just adding some extra numbers to their rolls. And if you want everything to be easier you might as well just assume you always succeed on every check and get max damage on every attack. For that matter don’t bother even pretending to be interested in dice, begin every combat by just describing how you massacre your foes. Then type up a description of it and you’re writing a book instead of actually playing a game.
