I feel like Superman, WW, and DD are all 5-5. Superman has everything he needs to still get close to Sinestro. At close-range, F23 still has to be respected. His ability to take 50% then put you in a cross-up dive mixup cannot be discounted. WoWo has too many anti-zoning tools to keep her away. Shield Stance is a PROBLEM for Sinestro.
DD is such an annoying character to fight. Good trait & meter management means DD is always in your face. I don't see how it's not even.
Zatanna is a 5-5. You play her like you do Ares. Sinestro can out 'footsie' her and she can't really stop you from charging trait. Once you have trait, you can bully her a bit.
Hawkgirl is not a 7-3. She has tools to get in your face and stay there. Most HG players are not fighting this match-up correctly. It's in Sinestro's favor as a 6-4.
GL is not a 7-3 either. He needs one right guess to put you in a repeatable 50/50. I agree GL's poor mobility means he's always at disadvantage against Sinestro, but he has the tools to get in. His low starter is annoying as hell as it goes under B12.
Lex as an 8-2? 7-3? Ok. Not 8-2. I need an explanation.
Flash....I cannot see this being even. He can punish everything you do. Maybe I am fighting this MU incorrectly, but it seems like you cannot zone him and his little foot poke beats everything Sinestro can throw out there.
Aqua, Flash, Frost, MMH, and Scorpion are his toughest match-ups.
Okay, before I begin I should explain that I judge Sinestro's MUs on only a couple of criterion: can they stop him from getting trait and how do they deal with his zoning?
Supes: He can't really stop trait charge until he gets closer and his zoning is very limited against Sinestro. He must also be very careful with his F23 because if he is even a little off, it is a free whiff punish with D2 or D1. Pre patch Sinestro still did prety well.
WW: I don't really see how she can stop his zoning or trait charge. One of her best tools, instant demi-goddess, is almost always punishable by D2 or at least a FB. Shield stance isn't that big of a deal once Sinestro has trait because then she is forced to guess in his vortex and pressure constantly. He gets trait pretty easy once she is in this stance because of her limited mobility.
DD: It is true that DD will almost always get in at some point, but he is forced to eat a ton of chip due to his gigantic hitbox. DD is also one of the few characters that does less damage than Sinestro. The only thing guaranteed after a blocked Venom is D1, while all of DD's other options are risky and punishable. Sinestro can also make it so DD can never D1 ES outside of the corner; the floating hitbox allows him to avoid the second part of it and full combo punish him for trying.
Zatanna: I really don't see how this is 5-5. Sure you can trait charge and bait but she wins all trades, does more chip, and is safe unless you are really close. By the time you have trait, she usually has a good-sized life lead. Let's also not forget that one misplaced FB= a full combo after a teleport.
HG: I could potentially see it being 6-4, but I played PPJ while in Chicago and it seems as if my MU knowledge was confirmed. She does next to no damage midscreen, can't stop the trait charge, and can't fly ever against Sinestro. He can control her movement regardless of her positioning on the screen. The only time she is at advantage is if she happens to corner him.
Lex: I might concede 7-3, but my logic is that Lex can do absolutely nothing that he wants to. His trait and projectiles are too slow in comparison to FB, he can't stop the trait charge, and even if Lex manages to get the trait up, Sinestro can negate it completely with his own trait. His giant hitbox also forces him to eat a shitload of chip.
Flash: The only argument I hear for this not being 5-5 is that Flash can punish everything and yea, you shouldn't be using boulder or shackles in this MU. The only way he can punish FB is if Sinestro delays it, which means that he will either get hit by the MB every time or be forced to respect it. B12 outranges pretty much every attack that Flash has and Flash cannot saafely stop the trait charge unless he decides to do an unsafe special or if he is literally right in your face.
Let me know if you have any other questions.
