I was racing on Infinity and someone was walking to the 2nd nav because no hogs were available. A BFM admin said he could not walk this map even if no hogs are present for you to take.
I looked at the Rules and really didn't say anything like that......
"On Infinity, you may go back and forth to either side of the large structure at red base to check for hogs until one appears (or until a team mate picks you up, or you are able to hijack an enemy hog). You may also do the same at the back of the large structure, using team chat ("Y") to ask for pickup. Don't wait in the near vicinity of the flag—that is camping."
I was aware that you COULD walk until you see a hog, I thought it was under the saying "keep moving to the next nav"
