There's never enough Muay Thai scrolls. That elbow+knee combination is rarely seen outside of Red scorpion, and we still don't have a >>G as a flying knee strike.
Just make your own muay thai dude. Leave the another series on how its been planned. I highly doubt they will add a player scroll suggestion to the another scrolls. They might already have a muay set up. There has been a supposedly leak for another azteca scroll. Im pretty sure they already know which scrolls they will want to use. But please do make your own muay thai. Jaguar muay thai isnt in the game yet. Neither is tiger.
