If finding your mouse cursor is a serious issue for you, you might consider getting an add-on that changes the cursor. But complaining about a trivial gameplay mechanic that's old as dirt isn't interesting.

And ... finding the darned mouse pointer in a clutter of spell effects, Power Auras, MSBT text and doing so while moving is my biggest difficulty with both Fire and Frost specs. It isn't so much the time required as the detailed attention to a screen that is already drowning in data. Spamming targeted effects also requires a macro so that you don't instantly turn the effect off. Then spamming one key to trigger the effect followed by clicking the mouse button is very much a "clunky mechanic."
All those issues I mentioned are very likely not issues for excellent mages, but they are for the rest of us. I believe that Kyrilon was trying to state that it was a clunky mechanic and I agree with him.
