actually i haven't met any EX Skill that disable SS. Only met those that reduce stats.
GK - Striking Guard/Disable (FW) (disable opponent's SI, Volley, Header, Trick Shot)
DF - Power LShot Guard/Disable (LWF)/(RWF)/(FW) (disable opponent's Bullet Shot, Blockbuster)
Tech LShot Guard/Disable (LWF)/(RWF)/(FW) (disable opponent's Long Ranger)
Striking Guard/Disable (FW) (disable opponent's SI, Volley, Header, Trick Shot)
MF - Stealth Pass Guard/Disable (disable Stealth Pass and Killer Pass)
Chasing Guard/Disable (disable Chasing and Destroyer)
FW - Chasing Guard/Disable (disable Chasing and Destroyer)
Saving Guard/Disable (disable Quick Save and SoI).
imho, these could be the best EX Skill for each position.
Imagine u have 3 strikers equip with Chasing Guard/Disable, that would mean ur opponent's whole backline x boleh pakai dy. Coz usually for Level A SS DF is Chasing + Header, Chasing + Feed, Chasing + Cross. Means u might be able to disable anyone of them in the backline.
Or, ur GK and back four DF all equip with Striking Guard/Disable. Then ur opposition's frontline habislah..... SI, Volley, Header, Trick Shot all x boleh pakai.
Wah... thanks brian, good info
