I played a few Searing Rage players last night and it's night and day between which ones relied on the mid teleport and those who didn't.
Yes, ducking is a good way to not get hit, but you're not blocking, covering ground (moving back or forward), etc while waiting on it and Scorpion can just mosey his ass on up to you for next to nothing.
I actually don't mind the MU too much now because I don't feel threatened by a YOLO teleport at all times. Having the life lead and making them advance on me is a nice change.
