IME on all gigs, even the smallest, a little PA support for the Bass drum tightens up the sound of the whole band.

That's my thinking too, unless you have a huge kick drum that is well damped they sound poop, of course there are gigs small enough to not need it but then they are vocal pa and a combo sized amp as backline anyway ime.
