When using a bow you can either hold your mousebutton or click it. When clicked it will release the arrows as soon as possible = max accuracy. While clickshooting with a longbow, missing stationary targets at mid range is something you cant prevent, no matter how much wpf you have. Its just some sort of gamble sometimes. This also applies to other bows of course, but the longbow is the one most affected by this randomness because of the additional animation-bug-debuff.
Clickshooting isnt the most accurate, its about half a second after that. But still, I can tell you: With over 160 wpf on a +3 longbow, even point blank shots miss sometimes, similar but not so bad with warbow. You can be stood still, not having fired recently so your Xhair is small, and pull back and release an arrow at an enemy so close they COMPLETELY fill your reticule several times over, and it is STILL not guaranteed hit.
Combine that with: mid-animation hitboxes not being anywhere near the model, arrows sometimes passing completely through players, bucklers and shields that intercept arrows in the air, the odd random arrow that goes into warp drive and vanishes: Melee have it MUCH easier than it should be; archers sometimes get lucky, but always get whined at by players who think because they can block and attack they know how to play the game.
EDIT: I remember a time, after the wpf - weight reductions and the slot system, I could play as attacker on siege without even using a melee weapon, shooting everything that came at me as I walked to flag, and there was STILL only half as much WHINE about it. Then all the crying got worse so I traded for melee weapons: The only ranged that is bothersome is throwing, because nowadays the accuracy on pure thrower isnt that much worse than archers, and their DPS is ridiculously higher. And crossbows ingame are the same as real life: So bundle of sticksy that the Pope banned them from being used to shoot Christians, they are just SO gay, why would u spend half your time in a fluid combat sim, standing still, bent over? makes no sense.
