Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Technically, you could do away with i entirely in QM and not lose generality. But then you'd be stuck with 4th order differential equations. At least that's what one of our Optics profs claimed. I never checked myself, because you do not want to do 4th order PDEs anyway, unless you're a mathmatician or some (other) kind of masochist.
