I think this is what people think, but beyond the low guns being unfairly safe, nothing would suggest that DS was built to completely zone characters out. --- Probably not completely, but the guns were clearly designed to play a tremendous role in Deathstroke's gameplay. Currently, high and low gunshots are worthless outside of being anti-zoning tools in many match ups. Test Your Might scrubs, and other scrubs on social media websites such as Facebook and Twitter to name a few, are the main reason Deathstroke was transformed from a primary zoning character to a footsies and rush down character. As a high level player, you ought to accept this premise, not side with scrubs and anti-zoning zealots.
Being able to zone and doing the chip he did was what pushed him way over the top. He already had a top notch neutral that is his main strength, and always has been. --- Top notch neutral game? I think you are the only fool in this community who has less of an understanding of footsies than I do. Aquaman and Martian Manhunter have a neutral game that is deserving to be called "top notch". Deathstroke, on the other hand, has above average footsies at best, even with f+3 and j+3.
