Sort of. She can blink across entire maps in seconds, even through walls. But she's only able so many blinks at a time, and anytime a blink isn't immediately followed up with another blink or successful hit she gets stunned. So you gotta tele next to a guy and hope you're close/fast enough to hit them. And she'd also the slowest killer by a full meter-per-second, I think even slower than survivors. So she has to rely on her blinks.
It just takes way
too much effort to work, and the lack of a training mode means you don't even have the benefit of practicing.
