I do not have a problem with people who do this if this is the only way they feel they can win or enjoy the game. I just try to find ways to beat it. Sadly, I dont use teleport characters. So any advice on handling the gun spam followed by the jumpimg sword if you actually get close?
Don't let Deathstroke stray; always remember that. When you have him in a combo, end it with 1, F2 (it's a carwheel move that prevents the opponent from rolling away). Then he'll most likely try to do that sword spin move, at which point you could just block it and punish.
WW is great against deathstroke her jump df3 can close distances insanely fast and as long as you block you can punish that sword jump with a df3. But you have to know ww a little for it to work but I don't know who you use.
