I'm guessing powerfists, whips and clubs are best for agility assuming skills are gained in relation to their contibution to pro standing.
All these weapons contibute 40% from hit and 140% from damage, where as guns contribute 60% from hit and 20% from damage (shortblades/longblades do 40% + 0%)
In addition, evader contributes 160%. So best thing to do is grab a powerfist and dive into a spawn
but it's not gonna be nice to your armour.
