Batman's trait is what makes him better than Deathstroke. Otherwise they would be on equal ground IMO.There is no way in hell Batman is top 5 IMO. He's really solid and has an answer for most things, but I can't see a character with bad wake-ups, lack of true mix-ups or 50/50's (other than grapple resets), tons of holes in his strings, a poor poke, lack of range, lack of solid whiff punisher (unless you're whiffing right in his face), iffy anti-air (his D2 has its uses but it's inconsistent), and other "weaknesses" being top 5 in a game like Injustice, where other characters have much more overwhelming tools and match-ups in which they dominate handily. Yeah, Batman's trait is great, his J2 is awesome, and he's well-rounded to where he's never helpless in any match-ups, but top 5? Serious question: What makes Batman that much better than Deathstroke. Deathstroke has better zoning, better anti zoning, better 50/50's, better oki and much better wake-ups. I'm not saying DS is better, but if we agree that DS is upper mid tier, then how can Batman be top 5?
If Deathstroke had a really good trait he would be a candidate for top 10 all day.
Edit: I read your second post and you make some good points. Batman and Deathstroke are maybe more equal than I thought overall. I still think Deathstroke would be top 10 if he had a good trait though.
