Nice example of Zed's safety

At 3 minutes, look at how Zed goes in. He obviously makes a huge mistake right there, but his kit lets him press one button to jump out of any harm or misplays. I always thought that if an assassin were to go in, they have to stay in the fight and finish their target, not jump out when a mistake is made. That should be an assassin's weakness, given how strong their killing potential is.
