No, I wasn't at PDP, unfortunately.
General sidenote about EX dash...there's enough leeway in between the first and second hit that fast uppercuts for sure stuff it if you crouch block it, and you can likely get tagged with an armored move from stand block. I'm not sure if everyone can uppercut punish it, but those that can will give Reptile a lot more fits in the corner.
Vs Sub...some more stuff I've come up with...
Obviously from full screen, your forceballs are a lot safer and a lot more dangerous for Sub if he's not sitting on EX. I'm finding it more and more effective to play lame from full screen, and force him to come to you. From full screen, you're at advantage. Fast forceball is good here. He has to use EX freeze to deal with it, and if he doesn't and you both trade, it'll be in your favor, for sure, because nothing for him is guaranteed at that range. So pretty much baiting him into using EX freeze will help out a ton. If you get a forceball hit without getting frozen, dash in and start an offense. STAY IN HIS FACE IF YOU DO START PRESSURING! Do not let him get enough breathing room to clone, or you risk getting hit by it.
I think the match is much more manageable played like this. Just my experiences.
