Realism? Most people I know, you know, we all know... are not the epitomes of their Thing. Olympic athletes, maybe. Yeah, yeah, I get that most games are superhero/fantasy games on logarithmic scales, but even in the scale of a game system... it always bugged me how some players have this attitude of "Best or Bust". Not you, specifically, but Gamers Out There (aka: They).
I know a lot of players who enjoy "casual play", and those that are gunning to be on E-sports leagues/ladders. There are those that scoff and ridicule if your Fighter doesn't take Feat, Feat, Feat and Feat but your Knight better take Feat, Feat, Other Feat. Game systems that encourage this sort of behavior have, frankly, started to bore me. I think, personally, that this is where "Template starts" have started to crop up and become a thing. "Want a Good Fighter? Take this Template, and we'll kit you out. Take all the guesswork|creativity out of it for you."
It's the "Dude Do You Even Lift?" of the RPG player world.
