It would be awesome to preview armour with a ‘night time’ option, so that we can see sylvari characters’ glow effects.
Anet could add the ‘lightbulb’ icon in the armour preview/hero equipment interface (the same icon used in total makeover kits).
This, if implemented, would come in very handy when deciding which dyes to use (as we currently have to guess how the dyes affect armour at night, or literally wait until the night!).
