Make up the ability to live with other gear. All that is required for this char is that it be able to do all your MF runs without dying. Gear your merc nicely, make a good build, and hopefully you should be set. Although maybe you're better off just making a manual hammerdin for MF. But regardless, Travs have way more MF and they're cheaper. I'd just use those. Use some FHR charms if you must to get the breakpoint or whatever.
