After doing some testing with Hornbow and Arrows on DTV, I must say that difference between 160 and 184 wpf is quite massive. Draw speed has improved few times, accuracy is much higher and damage also. It's practically submachine gun build you're mentioning. It is necessary because I use Arrows and not Bodkins so headshot is usually only way to kill higher level bots.
Haven't tested Longbow yet, but I'll sure try to see how it goes. With Longbow and 184 wpf I expect similar draw speed as Hornbow at 160 wpf.

That's not competitive build and you know it. There is no reason to put 100 wpf in melee, other than reducing repair chance. Yes swing speed is much better and so is damage, but who cares when archers rarely get to fight in melee. Putting those 24 points in archery means a lot, much more than wasting them in melee proficiency.
If you want to change behaviour of archers, you need to allow higher armour which will slow them down (less kiting) and give them free melee wpf and reduce archery wpf a bit. Kiting, pure archers will still be there but new breed of melee archers will arise.
But if you keep it this way, only sensible choice will be pure archer.
