The difference between running while standing up and running while crouched is too small. you run like olympic long distance runner when in both stances with just a small change in pace.
crouched running should be a more tactical pace that enables you to move relatively quickly but in a more concealed way with lower silhoutte.
suggest half the BIS staff try running around their offices crouched vs the other half running while standing. see the difference in speed pls. try put that propotinaltey in the game pls.
its important as it makes the game feel very fast paced and arcade like.
