Might be down the line of paid DLC costume packs :\
Were they not slightly cloned versions of Ryu and Kazuya in SF X T though?
They were unique between each other, one was Ryu other was Kazuya
Here they "could" get a different moveset OR just have a Kuro alt costume for Toro as I say this is the best option for everyone and would be really easy to implement as uro model is in the game already.
I love Toro but I do love even more to play as Kuro.
Beside is not like he would be as close as over redundant as 2 Coles
(Both cats were pretty unique in SFxT).
Unique to each other, but just clones of other characters in the roster.
They were clones in the sense that Ryu and Akuma are clones however. They have different speeds than Ryu and Kazuya, different health, vastly different hitboxes (clearly), different utilities and supers, damage, etc.
