Yes but most campaign fights would be over before someone could get tags on and to the fighting area in some zones on an offensive fight because of where the C.A is compared to where the fighting takes place. A good 5-10 mins after the music starts for the npcs to show up would probably be better. Also the npcs still have a we zone at the other side of the zone bit. It's why even in the death throws of WotG people would get tags and then snipe the incoming npcs. I'm sure this might still happen at times. Other times I think the game is checking to see if the next battle is going to start as one is ending so you get the awkward is anything else coming pause time.
