Regarding 22A_22B:
(Wall on opponents right) 22A , W! . During this wall splat, the opponent is considered standing for a practically FREE attack! I've been able to connect 22A W! 6B,B,B > 1B > 2A+B > FC 8B BE > 3B BE > QI A+B BE > 66B BE > 4B,A for around 153 damage (the 6B,B,B and 1B appear to take on CH stun properties during the comb). This combo appears to be character dependent due to the 6B,B,B (I've connected it on male character, not any female characters). Sometimes you won't get the CH on the 1B. Also, other times, after the QI A+B BE, it would teleport me and leave me in BT (instead of facing my opponent) and my opponent would bounce off the wall, allowing for a BT A+B to finish for 143 damage instead.
A good meterless variation of this is 22A W! 6B,B,B > 1B > 2A+B > FC 8B for 103 damage. Wall on the opponents right side.
22A W! 6B,B,B > 66B > 3B BE > QI A+B BE > 3B BE > QI B > 3B BE > QI A+B for 149 damage . Wall on the opponents right side.
22A W! 6B,B,B CE 2 - 137 damage (time the CE when the bubble connects). Wall on the opponents right side.
Also, check this out - you can also connect 22A W! 44B > 66+A+B > FC 8B BE > 2A+B > FC 8B BE > 3B BE > QI A+B BE > 66B for 149 damage (yes, the old combo before the 1.03 patch). Wall on the opponents right side.
88A W! 44B > 66+A+B > FC 8B BE > 3B BE > QI A+B BE > 66B BE > 4B,A for 142 damage (wall on opponents left side).
In general, 22_88A W! 44B will combo on both sides, but which side you're on will determine what combo to do.
22_88A W! 44B > 66B+K - 88 damage
22A _88 W! CE 2 - 120 damage
22A_88 W! 1A > CE 2 - 181 damage (gotten as high as 210)
This seems like pretty good tactic for levels that have walls and ring outs - 11_77K on side ring edges versus 22_88 A agains the wall. 22_88A also rings out if close enough on hit at the ring's edge.
