I honestly suggest not using any add ones that alter her teleportation distance. An extra teleport sure, or an add on that makes it so she recovers after, sure.
The main thing that helped me learn to use her well was to focus on getting used to her base teleportation distance so you can better estimate the areas you're going to appear at when you use the power.
Tried her out a bit a while back and gavw up on learning her. Now i want to try again. Any tips other then learning to predict?
Don't wait on reaching R1 as any other killer to start learning her. You'll get stomped and not learn a thing. You won't even have enough time during matches to practice your blinks.
