I think Sindel should be a playable character because she is one of the best mk woman ever. In mk9 she was so easy to use when performing a combo. Also, her xray was great. In mkx, Sindel actually DID make an appearance. But only the story mode. And right now, Sindel is a NPC that you fight against in the story mode. Same with Rain, Baraka, and Tanya. I mean if Tanya is a dlc, then so should the other nonplayable characters that didnt make it to the mkx roster. Also, i think Sindel will have very cool variations. Her first variation could be when she uses her screaming powers, and have combos utilizing her screaming powers. Her second variation could be when she has special moves that are containing fireballs that she shoots from her mouth. Like in mk9. Her final variation could be her having step up move combos and her using special attacks with hair whip move. Another reason why Sindel should be a playable character is that she has character ties between Kitana and Ermac. Sindel was also a fan favorite. So those are my reasons why Sindel should be a playable character.
