Johnny Cage had (arguably) the best restand move in MK9. He could end every combo in a restand, just like the MB throw in MKX. Did that mean he was a 50/50 character and would win if he got the first touch until the opponent guessed correctly? No.
Kabal had an amazing restand that he could end every combo with, did that mean he had a 50/50 that would win the game if he started it? No.
Same for Skarlet.
Having a restand does NOT mean having a free 50/50.
Scorpion had a great restand and depended A LOT on his 50/50s. Was he broken and would win if he got the first touch? No. Was he a boring rinse and repeat character? No. He was tons of fun to play against and with and he wasn't even good. NOW IMAGINE IF HE HAD TO SPEND A BAR FOR EVERY RESTAND!
Stop thinking that having a restand for one bar means every character is going to be Batgirl. It's not. Some characters will have good 50/50s, sure. But the game won't be shit.
Get your shit together, people, and calm yer tittes. The game is going to be awesome.
