Agility, compared to Srength is seriously OP.
But nothing won`t change, because the majority of "good" players are agility whores, thus lobbying for it to stay strong.
There's still an argument for Strength. We like to think that if we get lots of kills that's down to our superior skill at arms but much of the time it isn't: we kill an enemy by hitting him from behind when he's being ganked. Equally we die an awful lot of the time because
we get ganked by enemies and can't do anything about it. In these cases, skill doesn't matter. Strength does on the other hand, because it lets you have nastier weapons with more PS, so making it more likely that your blow will kill an unfortunate gankee and it improves your health and allows you to put more into IF so that when you get into trouble you might survive long enough to escape or be rescued.
