Mei

Endothermic Blaster

	Freeze (slow) duration increased from 1 second to 1.5 seconds
	Weapon alternate fire ammo cost reduced from 25 to 20

Developer Comment: Increasing Mei’s slow duration helps her freeze targets that are particularly elusive such as Genji or Lúcio. Lowering her alternate fire ammo cost allows her to more safely use it without costing her the ability to freeze enemies.
