The way DRK stands is okay, but the running animation looks like you're trying to shovel snow along your driveway or something. It's the main reason why I dropped it after getting to ~50, I just can't stand how stupid it looks. People can harp on about how it's 'realistic' or whatever, but I think the entire game concept is beyond realistic at this point. If they had a running animation more like the SAM one, I think it would be better.
