Fujin and Ermac for MK 11
Cassie is powerful and dangerous with her restands, her pew pews but can be countered. I respect her above Black, Scorp, Geras etc because her level of execution is higher and there's a reasonable amount of skill involved. The other 3 I can't say the same. They're braindead compared to Cassie. KL is also a prime example of this, just look at the % of E.Blacks, Scorpions, Geras etc players used compared to Cassie players.
