You really can't, tho. That's the issue everyone has. It's on GCD (pretty sure) so you can't just use it instantly over and over; there's a few moments of waiting between use. And if you're trying to spam it but you get pulled by the last draw in immediately after you've warped, you're really not left with enough time to get away to avoid fatal or near-fatal damage. And evidently latency issues compound the problem.
