low prority but doesnt make it useless.
generally something performing not at high utilisation and not faulty will respond to pings in a timely manner.
also what is worth thinking about is its icmp thats usually deprioritised not udp, so you can do udp or even tcp pings.
also I rarely see end points have bad ping responses when they working normally, its normally just some intermediate routers that respond slow.
