If the weight is such an issue why not drop your bow to fight rather than hoisting it over your back?
Forgive my ignorance as i havent played ranged since the last patch but if you drop you bow n arrows on the ground, you will surely do better in melee? You loose your ability to kite but improve you ability to fight.
I would also question your premice that you need high wpf to effectivly melee. Its easily possible to do well with low wpf chars when u have light armor and high ath.
I think a change in player mentality was hoped for by the devs, one that has not yet occured. I for one think they should further reduce long weapon speed and make mid tier weapons the more effective when speed/length/damage is calculated. This i believe would go someway to narrowing the gap between pure melee and hybrid functionality.
After the changes, I sometimes dropped my arbalest when I entered melee.
Sometimes that meant I couldn't retrieve it because the enemy had taken that position, but most times I could get it back. This added a sense of strategy. Did I drop the arbalest to gain movement speed for the melee fight, or did I keep it on me in case I wouldn't be able to retrieve it? If I sudddenly got surprised by enemies that came around a corner and had to run from, did I keep the arbalest and risk getting caught or drop it to safely get away? When someone managed to sneak up on me, it also meant I had a disadvantage in the melee fight, I didn't get to prepare myself.
Before you just had to choose from run/stand and fight when enemies came close, now you have to make choice. Drop and run, sheath and run or stand and fight? With or without the weapon on your back?
Making the choice of whether or not to drop your ranged weapon adds to the game. Figuring out if you should drop your ranged weapon or not, and when to do it, is a skill in my opinion. Sometimes you choose the wrong option, other times you don't. Consistently doing the right tactical choice is the mark of a good player.
Also, I agree with Casimir. 100 wpf is all I need for any melee weapon, 50 is still doable. I had 100 melee wpf in my crossbow gen, my HC gen and both y archer gens. You don't lose much from it.
