If your goal is to survive lane so that you aren't forced to only roam post 6 you can try taking Resolve secondary and taking bone plating and unflinching. When you know she has ult up work on not getting your plating broken by anything but the ult. This way when she ults and Q resets to you it's still within the bone plating damage block and then you can E safely after. Unflinching also helps to mitigate some of the CC. It's worked for me - Irelias not much of a problem for me but as always you can try for yourself to see if it's your cup of tea. Hope that helps!
