That's where you build Ninja Tabi that already reduces 10% of AA's and lay over a Randuins or Frozen heart. If you really hate ADC's you could even consider a thornmail.

And don't give me the "But I need Merc Threads on my Bruiser" crap, since season 3 took care of all your tenacity needs and then some.
