Actually, I get pretty much the same items you do. I only modify them slightly depending on what we're playing against. If they have a lot of ability to get away and CC, i'll build Rylai's instead of Rabadons, depending on whether I need to produce more damage or survive more.
When I build, I look for items that add to my CC. Having my Q not only pull them back but slow them as well is a huge advantage. And Liandry's Torment or whatever it's called cares nothing for their MR, as it does damage based on their HP, plus it gives you some HP as well. So it's an alternative if you're planning on being offensive, as opposed to a CC asset.
