Disagree with the at least 150.
Unless you're going AGI archer than yeah, but if you're a STR build like me it's not going to destroy you if you don't have the crazy amounts of WPF people talk about. For PD 6? You prolly need like 120. However I do agree with NOT putting ANY other wpf points into anything but archery. 2handed archers are too spread out imo. I can take a 2handed archer with my 1wpf langes messer and still do fine (PS 5).
And then when it comes to range I completely annihilate them with power, speed, and accuracy.
