So I did 6T vs a wall and looked at the health bar..

This move gets weaker when there is a danger zone/wall behind them, like really, really weak.
I'm not sure if this is a common thing but I figured using the danger zones / walls would generally increase damage input.

no dangerzones/walls 42 dmg
regular wall 25 dmg
dangerzone wall 30 dmg

That's because you're doing it wrong or at least you're not pushing that ridiculous ass wall throw to its fullest potential.

Press P+K when you see combo throw on the screen. Then go from there. Whatever it is you do will do stupid amounts of damage.

If you press 6k it causes a wall splat and 8PPP works like a charm. But there is plenty more he can from the follow up after that wall grab.

Damn I'm such a noob.. It's even in the move list .

Thanks for the help I'm going to the lab with this now.
