I have it macroed for raise but for double press rather than a wait; just two lines (use Swiftcast/use Raise) and I mash the button to raise someone. It works fine for me.

Then I also have it separately on my second hotbar for use with other spells, as I frequently swiftcast all kinds of things and want to be able to decide freely. I pretty much never want to hardcast raise unless there's no alternative, so I slapped them together in a macro to save me panicking looking for two buttons in a death situation.
