I might be crazy, but what if we made wits end into a dual resist shred item?

For example: Wits end - 3400g Components - Recurve bow + Jarums fist + 1200g

Stats - 50% attack speed + 350 hp

Unique passive: Deals 15 physical and magical damage on-hit.

Unique passive - On Edge: Each instance of magical/physical damage dealt shreds 3% of enemies bonus magic resist/armour, stacking 5 times (max 15% shred) reduced by 50% for ranged champions (max 7.5% shred).

(the greater of the two shreds is applied in the case of two instances from differently ranged champions inflicting the debuff)

This item is intended to be that item to help the hybrid champs who have trouble dealing damage once a target doubles up on their resistances, and is in fact not very cost efficient when the target only has one resistance type. This is supposed to be for the Jaxs, Shyvannas, Udyrs and Volibears out there (and the range reduction is to stop kog from going apesh*t)

What do you think?
