Honestly, I think people overlook the fact that you can play D&D and take out most of the rules for players who aren't rules heavy without really impacting the game for the rest of the table, who can still use those rules.
If you honestly only want to roleplay or hang out with friends, it doesn't matter your class, just attack, use a cantrip, sometimes look up a spell for funsies. If you are serious, you can get deeper into the mechanics and at least have a passable time.
This is something so many other RPGs fail to understand, and what virtually all discourse overlooks. It'll talk about, idk, Critical Role, streaming, name recognition, etc -- and all of these are legitimate -- but people keep playing the game and introducing others into the game because the game accomadates a huge swath of players and doesn't break in doing so.
We can talk all day about the encounter day and class balance, but casuals do not care about that. Most people do not give a flying monkey's tail whether warlock and fighter and wizard feel exactly perfectly balanced throughout an encounter day; they care whether the class at least works, does a little bit of fun stuff, and if they can have at least one cool, big moment every few sessions.
PF2E doesn't do this well. Warhammer doesn't do this well. OSR games doesn't do this well. These games require some kind of thinking, either mechanical (for PF2E), or narrative (for OSR). But in 5E, I can roll up a warlock, fire eldritch blast, maybe drop a hunger of hadar or something, and feel good about myself. Then I can roleplay a little bit, roll some dice, and we're good. I don't have to figure out how to navigate a deadly dungeon with a 4 HP character while trying to figure out how my rope, rusty dagger, and bucket can be used to take out 20 orcs. I don't have to set up a mechanical combo with two other players in a highly balanced fight. I just have to hit my buttons and roleplay a bit. Easy.
I don't think most people in this thread will agree with me, and I think that's because most of you legitimately just do not understand how big this is for people. Yes, OSR games are great, PF2E is great, but they legitimately aren't as easy to play as 5E is, no matter how many rules they have or don't have or how well laid out the books are.
