Everytime I tested it out, Yosuke was always counter along with Labrys because the gears lingered.
Did the Yosuke that ran through your gears do a Persona Break?
He won't get the projectile invul until he actually dashes, so at the very least, whatever projectile's right in his face is gonna land.
Asides, if he does any dash whatsoever against 214214C/D, you both get counterhit.
If it makes you feel any better, I made a Kanji mad by constantly dusting him with Liz and Yosuke.
Sidenote: I just love Naoto's IK, especially when there's D traps everywhere.
