Gotta love strawmen.
Comparison:
In the old system the hybrid looses 35 wpf from his main and is at 82%, from his secondary he looses 80 wpf and is at 60% of max wpf.
In the new system he looses 28wpf from his main and is at 83%, from his secondary he looses 53 wpf and is at 69% of max wpf.
So, ok, that's the difference of 7, respectively 27 wpf, which according to your own statement is laughable.
But like bruce says, in the new system you also have to look at the price tag. In the old system the hybrid would just stack 2 snipers, steel bolts, tears and plate. (Eh, most people took sniper with them at 1 wpf...
)
In the new system the hybrid would just take one sniper and normal bolts, and will still have 18k less to spend on his melee gear.
This translates into weaker armor and/or heavier armor (armor wpf penalty...) and/or worse weapons (if you can find a weapon that is cheaper yet more effective, that's entire a problem of balance inside the category). Tradeoff is very much there (and I don't see anyone picking up a crossbow just for a few cheap shots).
