Guild Wars 2

from the update notes. what does it mean?

It means the graphic of the flames blasting out from the foe will not go out as far and not scale up so drastically in size with the size of the foe. It is to help lessen the flames taking up the whole screen during combat, especially in large group events.

oh ok. applied to Mighty Blow (Guard hammer 2) as well.

My guess is that it’s more likely not to be drawn (culled) in crowded situations.
