Kabal Vs Smoke is evenly argued 1/3 in favor Kabal 1/3 even 1/3 in favor Smoke
BTW, take note the point values for Kabal and H Smoke on the match up chart, Kabal 155, Smoke 147. The next highest is 136 which is why I grouped them since there's an 11 point gap, never seen again down the list.
Edit: A way to compensate would be Kabal S+, H Smoke S, but since they are at worst a 5.5-4.5, I don't think it's unfair to put them in the same category. S+ would be a character with no bad, or even matchups, and in the case of a 6/4 Kabal/Smoke, he would be S+. S would be no losing matchups.
Counter Edit: I will go through and regroup based on some mathematical match up good/bad/even counts and come up with a fair way to rank them. It'll probably still be similar based on points.
