Ana's ultimate, Nano Boost, apparently:
Increase an ally's damage and speed, while reducing damage taken
How much of a damage boost and speed boost are we talking here, and what is the damage reduction? How long does the boost last?
Does her damage boost stack with boosting abilities such as Mercy's Cadeceus, and does Lucio's Speed Boost stack with Nano Boost? Does reducing damage also factor in armor as well?
