I heavily disagree with this statement. Such a big advantage is only needed if noone plays coordinated. And i believe that is fair. If you don't coordinate, then you need to outnumber heavily to reach such a goal as a zonelock.Yep. This. Requiring a ratio of 1:3 or 1:4 seems to be the driving factor in being able to lock a zone, not necessarily how you move around the map.
If one side does not coordinate (aka zergs in a blob) you only need a force that can beat the enemy zerg and 1person for each BO.
Your mainforce follows their zerg, beats them, zone locks. Easy to say, hard to do...but that's where rewarding coordination comes into play.
I just made a huge post explaining my thought more detailed in another feedback thread...only just realised it might fit here better and is a bit OT in the other thread. If someone is interested:
