Seriously, if you used the wall of justice to kill AV, stop trying to justify it as strategy. You used an exploit, grats on your kill but your method was anything but strategy.
This doesn't make sense using someone weakness against them is the very defination of a strategy. You exploit someone weakness and turn it against them to win the fight.
Let me give you an example in a boxing match if your fighting a guy with shorter reach then you, you exploit his weakness; which is his short reach. You stay out of his range and knock the shit out of him because you have longer arms then him.
This can be applied to AV, AV weakness was he couldn't attack you through the wall so you exploit it and you destroy him. At the time it was a weakness intentional or not a weakness is a weakness. How is this not a strategy?
