Ok going off your thought process this is what I came up with
SK Speed 174 or higher brings AA and self clense
Brogni Speed 173 or 1 lower than SK bring sheild,block buffs att up when a3 booked
rest higher speed than SK and Brogni
Scabrius brings leech, weaken and poison
Toragi bring ally protect, sheld refelt damage att down and poison
Ninja brings def down and the pain
Now I can have higher speeds as long as I keep SK and Brongi in tune correct?
