I think a lot of people have a hard time WILDing, but once they figure out how to do it consistently, it becomes a preferred method. Once you get into the right state it's a lot less hit or miss than the other techniques. But getting into that state is what I've found difficult. I've gotten close heaps of times, but only ever entered a proper dream about twice. Most of the time I'll only get a few seconds of imagery and then either wake up or go unconscious.
