Edit: Posted in General Discussion as its not necessary a Bug. Yet.
Tests were conducted on a domination match on North American servers (both testers are resident) on Skim Junction.

This is an issue chalked up and reported here:
https://forums.dust514.com/default.aspx?g=posts&t=92132&find=unreadThe purpose of this thread is to lay down the ground work for a testing base contributing to this phenomenon. As such, we've ruled out two direct concerns previously brought up.
A.) That this is a map error in Spine Cresent. Common belief is that this phenomenon only occurs in a small gap at objective Alpha on the bridge. Videos show this is not the case.
B.) That this is associated with Lag. Being as we were on North American servers, this should not have been the case and even in a high latency environment testing would inevitably come out the same due to testing procedures.
What we concluded is that while the hit box may not grow larger - something CCP states there are not mechanics that could possibly occur in this manner - something IS happening to prevent the Scouts adequate access through previously passable locations when they sprint. More so than a Heavy, as we'll get to in a later video.
Test A - Scout with base movement speed

Warning: Includes crude speech from recorder due to disbelief as the Heavy's elbows barely clipped through the bumpers.

While this does not necessarily prove that a Sprinting Scout is easier to hit due to hitbox increase, it does invariably prove that ALL suits are less agile when sprinting as the collidable objects are very much more noticable. Turning corners, trying to squeeze through tight spaces and running past players/objects is difficult to manage when sprinting because of this oddity, whatever the case may be.
So does sprinting decrease a Scouts survivability? Thats still up for debate. If you guys have any other thoughts on how to more accurately gauge this, feel free to suggest something to us and we'll do what we can.
