Things I've tried: complete reinstall, setting graphics to fair, capping FPS @ 60, removing all addons, deleting the WTF, interface, and both cache folders, disabling automatic graphic switching, resetting the SMC controller, elevating the laptop up using a laptop stand (to help with heating issues), poking my eye, etc.
My system specs: Macbook Pro 15" (Early 2011), 2.2 GHz i7, 8 GB Ram, AMD Radeon HD 6750M 1024 MB.
Update: Something new I tried this morning was switching between the 32 and 64-bit clients (I was using the 64-bit above). No resolution there. Installing Windows now via Bootcamp and will try and reinstall WoW because this is just unplayable.
