my current build is going for 15 agility and 12 was slow as hell, i cannot recommend anything less than that!
with throwing 133 you won't be able to hit that easy, considering your PT is so high (i think higher PT reduces accuracy again or not? correct me if I'm wrong)
but my current build also has something 120+ wpf and i am only effective in medium close range and therefore always threatened with enemy melee takeover ...
but 24/15 or something could be fun (5 WM = 148 wpf, 8 PT, 5 ath, 5 points to put where you want)
