Healing reward
The reason people can walk through warding lines is Stability. However, if you time it right, you can get lots of people to at least whack into it once before they regain stability, if at all.
Generally speaking, most organized zergs get Stability up as they do the initial charge, so dropping your line then would generally mean it will be ignored. Try to time it for a bit later in the match to divide and disrupt forces.
