[@Penultimate_Pi] This I agree with.
I like Sonya and could possibly use her, but the reason I don't want to is because... It would feel awkward for me? 
Like, I mained her in every MK she was present in. I know her character well enough in all versions. But somewhere I feel I'd botch her aspects. Like, I know her moves like the back of my had. (Dear god, my MK comboes in MK9 and MK X when I'm focused.)
