I don't really understand the fixation on having a higher powerdraw than required. My damage with a strongbow and only 5 powerdraw is sufficient for the current state of archery in this game, and to get up to 7 or 8 powerdraw would require far more sacrifices in WPF than I'd be willing to give.
The fixation is a difference of roles. High Accuracy makes you an extremely deadly long range sniper.
On the other hand, my build with a warbow and 10 PD means my long range accuracy is significantly less at 130-ish wp, but on the other hand I can keep the reticule smaller for a significantly longer time, allowing me to hold my shot better. Also hitting like a truck means if I hit you, you feel it regardless of armor.
So, again, difference of roles. You are much better in shooting targets from afar (Sniper Rifle), while I am able to consistently bring down any horse that begins a charge on team mates or quickly break shields long before they close to melee (Machine Gun Turret). I absolutely adore bridge battles or urban fights due to this.
For the average user, I do suggest a concentration on WPF not PD, as it does make the Archer much more traditional, and not so mid-range sledgehammer support.
EDIT: Also the required minimum of 30 STR means I have a lot more grace against enemy archers due to the HP difference. It usually takes 5 or so bodkin arrows to bring me down, an advantage I greatly enoy when an archer takes the first "surprise" shot against me.
