You of course always want that everything works as planned, especially that your strobes fire when you want them to.
But sometimes the effects can be interested. Now I’ve shot images like this before but I loved the responses of the group when only my backlight fired…. to make a long story short, we ended up doing some more of these……

 
So make sure that you always experiment with your light setups, don’t always fire all strobes, but intentionally sometimes just fire a few or only one, you might be surprised.
