I think that's where the other element comes in. Is time. @Poeticas the difference between grinding the dungeon 100 times over a long span of time vs grinding the dungeon 100 times in a span of 3 days or less is the difference. Let's take ffxiv as the example game. You would probably spend 1 to 2 hours spamming end game dungeons versus someone who spend over 8 hours grinding the same dungeon (I have done that and still do in various games). The play style and repetitiveness becomes different as one is playing almost like it's a job vs someone casually playing. Now imagine condensing that time of completion per dungeon to be as fast as possible. Ex. It takes 30 minutes for casual players and 10~12 minutes to someone who's is rushing. Imagine that for 8 hours and more. (I think I've done a dungeon in 5 minutes before...) Eventually when someone play at that pace they'll do everything and is literally is repeating that for no reason other than they can just do it and continue at that pace.
@tihi have you played airsoft, paintball, or any type of physical contact sports? I played plenty of paintball before and that's a lot of competitive/pvp/grinding lol.
