so I was watching the new battlefield vid and notices at about 4 minutes and notices that the operative that was disguised had his feet lighting up where he ran, is this a perk for a class or does this just happen? if so the disguise ability is going to be pretty pointless

just wondering what you guys thought about it

I thought the same thing at first but it might just be that he was running on dirt.

the medics can give (self buff?) a speed boost which makes you faster for "x" amount of time simaler to adrenaline.

Okay, that ''dust'' effect is just bad :l
