WTF Is the point of the guards other than to grief people dueling?

Title says it all.

Pretty random, would be cool if we got a new dueling zone, instead of that custom epl place, need a complete flat zone with no guards waiting to touch u

Hello.
Guards are added just in case a player marked as a unfriendly-enemy target enters the zone, and to protect the mall/vendors.
