Er, what? Pace off 75 meters and try it, with whatever load you want to carry. If you sprint flat-out, you'll probably beat 15 seconds by a large margin, that speed is more of a jog. When I was late for a class in college, I'd run faster than that for a couple minutes at a stretch, in heavy winter clothes with a backpack full of textbooks. It wasn't too difficult, despite being overweight, out of shape and awake 3 hours earlier than I wanted to be.You just proved that RO2 avatars move way too fast and are far too agile - thanks for injecting some numbers so we can see just how ridiculous the game speeds are.
75m in 15 seconds is starting to look awfully speedy...
There's a case to be made for the poor health conditions of the typical WW2 soldier, but I have a really hard time believing they'd perform signficantly worse in active combat than a lazy computer nerd can manage.
