Yeah. At some point they get in... after eating 40% chip and letting deathstroke fully build his meter. The only arguments I've seen for him (or other aspects of the game) not needing a change is that no one knows how to play yet, or that it's ok because certain characters can get around it. First, if you have to counterpick, that means the game isn't balanced. No one should need that explained. And secondly, kowing the properties of all of your characters options can factually tell you that there isn't anything some of the cast can do about it. That has nothing to do with reading or execution or any other aspect of the game. Some characters are totally invalidated by his zoning, period.
Who cares about incorrectly posted frame data unless those specified frames are supposed to be reflective of the actual properties? If they actually showed the real and current data, every single person who doesn't main deathstroke would read it and immedieately say "haha fuck that shit."
As for speaking wihout bias... Wow... a deathstroke main and notorious zoner thinks it's ok. Yup, that's credible.
