Most of my SCH abilities are on macros and I agree they are incredibly useful if you do them right, but Lustrate is the one ability I would never ever macro. That is the one ability I need to be able to hit as quickly as humanly possible in a "oh s---" moment and have it work reliably. The thing with using macros is it requires a certain degree of disciplined timing, which is fine on most things, but not on your "oh s---" button.
