I concede that it's hard to find people to play other systems, but not impossible.

I don't think "I shouldn't read this system because I might like it less" is very sound. If you applied that to everything, no one would try anything new. Why listen to a new band when Mozart is fine?

I will die on the hill that DND 5e is actually pretty bad, though. It's complicated in all the wrong ways, the combat is surprisingly shallow most of the time, the adventuring day tries to force it into very specific cadences, it's shallow in its customization, it has a martial caster divide problem, the math is bad (flat probability can fuck itself), the magic system is incoherent, its support for the non combat "pillars" is lackluster... Pretty much every single part of the game makes me grind my teeth.

The only thing going for it is it's popular, and it's shallow in some ways that sometimes make it hard to make an ineffective character.
