Falls down too much
I started fooling around with Cassie specifically to learn the run mechanic. I think are putting too much thought into the execution and trying to so fwd, fwd, blk. The timing on it is actually really really lenient, and I've learned to do it as fwd, fwd+BLK. You can do it as two "beats" if you will, like 1,2 and then just watch yourself run and time the move you're cancelling run into. I wish i could explain it better, it would make run combos much easier for people.Here's the deal guys, the run cancel is kind of weird at first since it isn't MK9 block dashing....I will admit I didn't like it at first....but the execution is really not that bad once you get used to it. The thing that you want to focus on in my opinion is to work on learning when to cancel into the run to the point where you are confident that the run will be coming out every time. Don't worry about putting the entire combo together at first just get this step down. Once you are confident with ability to cancel into a run when you want then it really frees up your focus into executing the rest of your combos.
In time as the game is out longer, people won't even think about doing the run cancels they will just be muscle memory much like the way dashing worked in combos in MK9.
TLDR: I wouldn't get discouraged and seek out combos that avoid the run cancel. It will eventually become 2nd nature once you practice it enough.
