Well, I hate to be that guy, but this is probably never going to work out. This girl has no benefit to building crit at all. She loses all the tankiness she would usually have since her shield has no ap scaling with this build to keep her up when she jumps on someone. Also, since you're melee range, it's super easy to get kited. Plus, why would you not build Infinity Edge on a crit-based build? Like that's just absurd to me. If you want to make this build at least have a chance, you need to give it it's maximum potential.
