There is a fine line between realistic/arcade in games, more realistic it gets, less fun it becomes
I think when most people think about "realism" in games like this they imagine something that's actually not realistic at all, just sluggish and frustrating. Running at 5mph, stamina bars, falling over every 2 seconds, 1+ second sword swings and fights that take 10+ hits are highly unrealistic, but most people who suggest them say they would add to the realism of the game. They just have an idea of realism that is more like a BDSM school of game design.
A game can be both realistic and playable, the developers just have to conscientiously plan the mechanics so that it isn't just an overly complex or unfun sluggish slog.
