while reading the MKDA tiers list, I've read that Frost was a good character mainly because of her 'infinite combo'. What is it? and if she have an infinite combo, why is she not ranked higher then characters like Scorpion or Shang Tsung who unless I'm wrong, have no infinite combo? And btw do Bo Rai Cho have his forward+x + free throw glitch combo in MKDA?
thank you
