Snake's weight actually make him lose the D3 matchup. MK would effectively win more matchups, but he could potentially lose some others that he didn't before. Worth it? Hard to say. But his weight is definitely not a weakness atm, might not be optimal though. Snake is in a great class as in he gets cged only for being heavy, never for being a fast faller. The thing is if you get chaingrabbed for X reason, you may as well max out that stat since you already get cged for it. On the other hand, if you don't get cged for that stat, you want to be as close to possible as getting cged without actually getting cged. So MK is fairly close in that case, but not perfect. Worst example would be wolf, heavy enough and ffer enough to get cged in both case, but not heavy not ffing enough to actually give him a huge advantage like snake. Jiggs has the opposite problem. She never gets cged by anything, but she only gets disadvantages from her weight. MK is definitely not in a bad weight class.
