Actually, there are three reasons I rarely use backgrounds for anything.  The first is that they're usually not relevant to the action, and therefore distracting; the second is that they're a pain in the neck to draw, and add time to the process that isn't needed; and the third is that I usually have text filling up most of the space in a panel that isn't taken by the character or characters speaking, so there isn't even space to put add them!  Plus, of course, the fact that I knew nothing about backgrounds when I started.
