The eternity “new” effects are fine (since super adventure box patch) but I dont know why some effects from twilight and sunrise are removed in the eternity, it makes no sense for me.
“Warrior, guardian, and mesmer skills which threw Twilight/Sunrise now throw the standard sword(s), burst of darkness/light when drawing or equipping Twilight/Sunrise no longer occurs” or “Unlike Sunrise and Twilight, the sword is not thrown in the Whirling Wrath skill effect.” (from gw2wiki).
my suggestion is to add these effects even on eternity so it can be more beautiful.
