Well, that is the issue. It is not a tool that Highborn benefits from, but other characters do which may negatively affect match ups.
Admittedly, the anti-breakaway moves shown thus far appear to be rather slow, namely Scorpion's and Sub Zero's, and hence primarily usable after krushing blow d+2. So I am not yet convinced that this mechanic will alter the meta as much as NRS claim, which they may surreptitiously already know. The implementation is merely an appeasement to the critics, but we shall see next week. I am certain a handful of characters will have really good ones.
