Precisely. 5e's greatest strength is its' simplicity. A player who's never touched a TTRPG before will have a much easier time picking up 5e than a more niche system (although PF2e is definitely not bad on that front, 5e is just super simple and even has resources for absolute beginners)

But that simplicity is also 5e's greatest weakness. Once you're beyond the starting phase and understand how to play, then you realize how much stuff 5e is missing, you start noticing how some of the rules are oversimplified and unclear, and you REALLY notice how the game starts to get dysfunctional at levels 13 and above due to Quadratic Wizard and the fact that AC doesn't keep up with hitrate.

But 5e at its' core is a simple, robust system that's dead easy to homebrew for. So covering that weakness (and being able to keep finding players for your games) is entirely within the realm of possibility. And hey, unlike trying to mod an actual game, if you decide that at all costs you want to play an Actual Dragon? Fuck it, we Homebrew.
