Do you run faster with your knife out? [I have tried to test this, but to no avail.] I am aware you can get a small boost by jumping while running. I am also aware having the sprint perk increases your speed. I am looking for some documentation / proof that you actually do run faster with your knife out as appose to holding any other weapon and/or that the sprint perk is the only perk to stack with other squad members if they have the perk as well.
I heard through the 'grape-vine' that the squad-leader should have the sprint perk as the owner of the sprint perk gains a greater % of sprint speed than others in the squad and then squad members can just spawn on the squad leader once he/she reaches the objective. (I.E. = Squad leader gains 30% sprint increase for owning the perk, while everyone else gains 15% sprint increase - falsified data, just an example)
This actually matters on Metro, when it is a sprint to objective B.
EDIT: I am still looking for proof. Everything I have found has been inconclusive / speculation. I do not want links of mere claims, Either from DICE or a reputable source! I have already tried contacting EA via twitter - but yet to gain a reply.
