Hmm, let's shoot passion at each other instead of paintDid someone say Russians? Did they say Joy? How aggressive (in behavior) is Dynasty, really? The lang is very passionate, but not aggressive. I think we need passion to 'move on', not aggression.
my take is that aggressive playing style (always moving up, doing stuff fast and taking opportunities for muggins and run-throughs) doesn't have to be linked with aggressive behaivour (although you do need adrenaline which is linked (im not sure how much)), and in fact aggressive behaivour results in the opposite of improvement, it leads to grudges, fragmentation, negativity. Passion is what drives people to do great things.
But seriously, it's just another tactic, so i say use aggression how you will, but don't be surprised if you have to suffer a side effect
