Guild Wars 2

What is the special effect of glyph of storm in air? I still cannot figure it out. Fire does more damage, water freezes mobs, earth blinds mobs, and air…?

Air gives a wide area of effect, little actual contact with enemies (damage), and the least amount of active time, BUT it looks cool, right?

Earth bleeds as well as blinding. Air just has multiple strikes like a small meteor shower. Best off sticking to earth/water for now.
