Everyone is really hyped for the new agent and that is absolutely awesome however, there is always the concern that an agent might be overpowered at release. After all, her ability to run and gun seems unparalleled. This however could be a repeat of Yoru and our false judgement when you consider these factors:

Sentinels. As it currently stands, every sentinel has an ability that slows movement, stops players, or wastes time. And seeing as how the character is speed based, I don't think she will necessarily be an exception to this. Imagine using your speed boost only to get stopped in your tracks immediately by a Cypher wire forcing you out of your ability. Or perhaps a slow orb or chambers trademark or that dreadful killjoy turret immediately making that speed useless due to a couple shots. With this in mind, she will probably have to combo her abilities if she wants to entry unlike Jett which in my opinion makes Jett a bit better than her.

Other than that, her ult is definitely good and will probably screw up my muscle memory. I also think that it is pretty cool that they added the cool ability where on kill the enemy immediately starts typing in chat.
