I was playing tonight and noticed people busting through some of my old frame traps and I could not get the double manual on instinct, I usually do mk mk or mk hp. I believe the changed advantage on block of lk and crouching lk from 2 to 1 and maybe changed some more stuff as I was pulling the old numbers from http://www.primagames.com/games/killer-instinct/feature/killer-instinct-frame-data-analysis-jago. Also I believe the might have change the frame advantage on instinct, I believe it use to be +4. So it looks like they might have nerfed jago on the last update.
