“Glamour skills cause confusion for 5 seconds to foes who enter or exit their areas.” This doesn’t seem to work on cast, for example dropping “Null Field” (or any other glamour ability) will not add confusion. This seems like a bug, as on cast they have been forced to entered the skill field.
If this is intended it seems a little harsh on confusion Mesmers who play PvE, most enemies at range will not rush at you to attack, never leaving the area to trigger confusion.
I have also noticed that while allies attack through glamour fields a heart with the condition “confusion” will appear but the condition isn’t applied. Any insight on this would be greatly appreciated.
