Jab-tilt works on shield but Zetter dash attack to up smash doesn’t. Feels like neither should work on shield so that pressure is less strong on shield using jab.
I could be extremely wrong here, but I don’t think jab tilting counts as a gatling. Zetter is (for now) the only character with an actual gatling combo.
kragg has pseudo gatlings, he can dash attack into tilts instead of upsmash
