Just don't let the click become a crutch. I now a TON of bands play live to a click these days. But, it kinda seems like cheating to me. Anyway, play live with a bass player and rhythm guitarist. Maybe not even songs. Just groove. Play a beat, have them join in, and just keep it rolling. But, if you get to the point where you feel like you need a click, I think that will cause more negative than positive.
