Deathstroke looks weird, not sure what kind of character he will end up being. Trailer didn't really give a good impression of him overall, it showed 4 strings, a command normal, and 3 specials, he should have at least 3 more specials.
He doesn't seem super combo heavy, all the specials he used knock the opponent far away from him, the anti air machine gun, the pistol shots, and the sword flip. His projectile seems to have some high recovery so I'm not sure if he is really supposed to zone with it, its definitely not as good as Stryker or Harley.
Nothing he showed could really be his hero trait.
Wish they did character walk through's and went over every aspect of the character, and there are no real trade shows, so probably going to have wait until the game is out to actually get any good bearing any of the new characters.
