Time to grade.
You get a D for DOWN PLAYING. Upon further analysis, however, I will have to add a minus to the D because everyone knows if you used Deathstroke, you would complain about how most of his match ups are 5:5, how few match ups you win 7:3, how hard you have to work to win, how Zod is broken because you cannot win, etc. etc.
In other words, your Batman down playing would be transferred to Deathstroke and you would complain about the same things. Hence your final grade is D-.
You graded unfairly, I'm going to have to take my report to the guidance counselor to complain about grade discrepancy.
I'll agree Batman's zoning is better vs some characters, Deathstroke zoning is better against some characters. Zoning is a wash I guess, they're even.
You can't say Batman's interactable control is better just because of one stage. Deathstroke's overall interactable control is better for sure. You really can't toss interactables at Deathstroke, he will just quick shoot you or air shots.
Deathstroke's corner game is by far better, I can't let that even be argued. He has a meterless vortex in the corner that is over 30% that ends in a hard knockdown with sword flip. After the hard knockdown you have to guess high or low or crossover, if you guess wrong you eat another 30+% into a hard knockdown into another guess. This is meterless. Batman's corner vortex needs meter and takes the same amount of damage, also if Batman crosses his opponent over in the corner he lets them out of the corner. Deathstroke keeps you in the corner no matter what option he selects. DS corner game is by far better and cannot be argued.
All downplaying aside, Deathstroke is a much better character than Batman and you need to admit that. I'm not even really downplaying, I actually have been upplaying Batman for months but now I finally have seen the light. So my point is you cannot call Batman top 10 without calling Deathstroke top 10 as well. It's just obvious DS is the better character
